Snake-Mimicking Sphinx Moth (Hemeroplanes triptolemus): the caterpillars of this species are able to mimic snakes by turning upside-down and inflating the area around their head

It's very common for moths to engage in mimicry during the larval stage of their development, and their caterpillars are often known to mimic snakes. In most cases, they'll simply mimic the snake's eyes (or eye) and its general morphology, but there are a few species that take their disguises to a much higher level, mimicking the snake's eyes, scaly texture, coloration, posture, and even its behavior with such a startling degree of accuracy that the tiny, harmless caterpillars are often mistaken for actual snakes.

Hemeroplanes triptolemus is probably the most famous example of this.

Above: a caterpillar of the species Hemeroplanes triptolemus displaying its defensive posture

This species of sphinx moth can be found in the rainforests of Central and South America. When threatened, the caterpillar suspends itself from a twig, turns its body over to expose its underbelly, tucks in its legs, and inflates the anterior segments of its body in order to mimic the shape of a serpent's head. As the body segments expand, several markings on each side of the caterpillar's body are exposed, mimicking the eyes and nostrils of a snake.

Above: the caterpillar is shown hanging upside-down; its actual head is visible near the tip of the "snake nose"

As this article explains:

At the slightest hint of danger—be it a stooping bird or pouncing lizard—the sphinx moth caterpillar begins its masquerade. Dangling from a twig, it reveals an underside patterned in faux snakeskin and eyespots that appear to glisten. By sucking in air through tiny holes in its surface, the caterpillar inflates its head to create the illusion of a triangular skull swollen with venom glands. If the shape of a deadly snake isn’t enough to startle away a hungry predator, the caterpillar will lunge as if to strike. And despite the larva’s comical lack of any actual weaponry, the strategy appears to be effective.

Above: detailed photos of the "snake's head"

This disguise is only present in the final instar, which is the last stage of development before the caterpillar undergoes pupation and then matures into an adult moth.

As I've said before, moths are some of the very best mimics in the world. I've also written posts about wasp-mimicking moths, moths that mimic jumping spiders, a moth that can mimic a broken birch twig, a moth that disguises itself as two flies feeding on bird poop, another snake-mimicking moth caterpillar, a moth that mimics a curled-up leaf, a moth that mimics a cuckoo bee, moths that mimic hornets and bumblebees, and a moth that can mimic the leaves of a poplar tree.

Yellowjacket-Mimicking Moth: this is just a harmless moth that mimics the appearance and behavior of a yellowjacket/wasp; its disguise is so convincing that it can even fool actual wasps

This species (Myrmecopsis polistes) may be one of the most impressive wasp-mimics in the world. The moth's narrow waist, teardrop-shaped abdomen, black-and-yellow patterning, transparent wings, smooth appearance, and folded wing position all mimic the features of a wasp. Unlike an actual wasp, however, it does not have any mandibles or biting/chewing mouthparts, because it's equipped with a proboscis instead, and it has noticeably "feathery" antennae.

There are many moths that use hymenopteran mimicry (the mimicry of bees, wasps, yellowjackets, hornets, and/or bumblebees, in particular) as a way to deter predators, and those mimics are often incredibly convincing. Myrmecopsis polistes is one of the best examples, but there are several other moths that have also mastered this form of mimicry.

Above: Pseudosphex laticincta, another moth species that mimics a yellowjacket

These disguises often involve more than just a physical resemblance; in many cases, the moths also engage in behavioral and/or acoustic mimicry, meaning that they can mimic the sounds and behaviors of their hymenopteran models. In some cases, the resemblance is so convincing that it even fools actual wasps/yellowjackets.

Above: Pseudosphex laticincta

Such a detailed and intricate disguise is unusual even among mimics. Researchers believe that it developed partly as a way for the moth to trick actual wasps into treating it like one of their own. Wasps frequently prey upon moths, but they are innately non-aggressive toward their own fellow nest-mates, which are identified by sight -- so if the moth can convincingly impersonate one of those nest-mates, then it can avoid being eaten by wasps.

Above: Pseudosphex laticincta

I gave an overview of the moths that mimic bees, wasps, yellowjackets, hornets, and bumblebees in one of my previous posts, but I felt that these two species (Myrmecopsis polistes and Pseudosphex laticincta) deserved to have their own dedicated post, because these are two of the most convincing mimics I have ever seen.

Above: Pseudosphex sp.

I think that moths in general are probably the most talented mimics in the natural world. They have so many intricate, unique disguises, and they often combine visual, behavioral, and acoustic forms of mimicry in order to produce an uncanny resemblance.

Several of these incredible mimics have already been featured on my blog: moths that mimic jumping spiders, a moth that mimics a broken birch twig, a moth caterpillar that can mimic a snake, a moth that disguises itself as two flies feeding on a pile of bird droppings, a moth that mimics a dried-up leaf, a moth that can mimic a cuckoo bee, and a moth that mimics the leaves of a poplar tree.

Moths are just so much more interesting than people generally realize.

Sculpture of a Woman with Four Children, from Mali, c.1100-1450 CE: this sculpture was created in the ancient city of Djenné-Djenno

Created during the 12th-15th centuries CE, this sculpture depicts a woman sitting cross-legged on the ground, with two children on her lap and two more clinging to her back. Scarification patterns are visible on the woman's temples, and there is a thick, undulating line running from her forehead to the nape of her neck, likely representing a serpent.

As this article explains:

Snakes on Inner Niger Delta sculptures are a common element and should be seen as a positive iconographic component. They represent control of a potentially dangerous benevolent power that must be tamed, domesticated, nourished, and satisfied so it will continue to provide protection.

This is one of the many terracotta sculptures that were produced in Djenné-Djenno, located in the Niger River Valley of Mali, in West Africa; Djenné-Djenno sits just to the south of the Medieval city of Djenné, which is still a major center of Islamic scholarship.

The ancient city of Djenné-Djenno dates back to at least 250 BCE, making it one of the oldest cities in West Africa. For centuries, it also served as one of the largest urban centers/trading hubs in the region, with a peak population of about 20,000 people. The city began to decline in the 9th century CE, when residents (and trade) began moving northward to the nearby city of Djenné, which had just recently been founded by Muslim traders. Djenné-Djenno was ultimately abandoned by the end of the 15th century.

Unfortunately (and unsurprisingly), most of the artifacts from Djenné-Djenno were looted or destroyed by colonizing forces during the 19th-20th centuries. Some of those artifacts have been repatriated in recent years, and there are ongoing efforts to return more of them.

Why Western museums should return African artifacts.

Child's Sock from Egypt, c.250-350 CE: this colorful sock is nearly 1,700 years old

This sock was discovered during excavations in the ancient city of Oxyrhynchus. It was likely created for a child during the late Roman period, c.250-350 CE.

Similar-looking socks from late antiquity and the early Byzantine period have also been found at several other sites throughout Egypt; these socks often have colorful, striped patterns with divided toes, and they were crafted out of wool using a technique known as nålbinding.

Above: a similar child's sock from Antinoöpolis, c.250-350 CE

The sock depicted above was created during the same period, and it was found in a midden heap (an ancient rubbish pit) in the city of Antinoöpolis. A multispectral imaging analysis of this sock yielded some interesting results back in 2018, as this article explains:

... analysis revealed that the sock contained seven hues of wool yarn woven together in a meticulous, stripy pattern. Just three natural, plant-based dyes—madder roots for red, woad leaves for blue and weld flowers for yellow—were used to create the different color combinations featured on the sock, according to Joanne Dyer, lead author of the study.

In the paper, she and her co-authors explain that the imaging technique also revealed how the colors were mixed to create hues of green, purple and orange: In some cases, fibers of different colors were spun together; in others, individual yarns went through multiple dye baths.

Such intricacy is pretty impressive, considering that the ancient sock is both “tiny” and “fragile."

Given its size and orientation, the researchers believe it may have been worn on a child’s left foot.

Above: another child's sock from Al Fayyum, c.300-500 CE

The ancient Egyptians employed a single-needle looping technique, often referred to as nålbindning, to create their socks. Notably, the approach could be used to separate the big toe and four other toes in the sock—which just may have given life to the ever-controversial socks-and-sandals trend.

Hedgehog on Wheels, from Iran, c.1500-1100 BCE: this 3,500-year-old figurine of a hedgehog on a wheeled platform was found with several similar artifacts depicting animals on carts

The body of the hedgehog measures just 2.8cm long (about 1.1 inch) and was crafted out of limestone, while the cart was made using a bitumen compound. The hedgehog's feet are attached to four round sockets located at the front of the cart.

There are eight more empty sockets at the back of the platform, and their pattern/spacing could indicate that two smaller hedgehogs were originally mounted on the cart just behind this larger one, like a pair of baby hedgehogs following their mother.

The hedgehog was found with another figurine depicting a lion on a wheeled platform. Both of these artifacts were unearthed at the Temple of Inshushinak, located in what was once the ancient city of Susa; they date back to the Middle Elamite Period, c.1500-1100 BCE.

Their original function/significance is still widely debated, with some experts arguing that they were created as toys, while others argue that they were used as votive offerings. Their presence in the temple suggests that they likely had some cultural/ritual significance, but it's important to note that those two explanations may not be mutually exclusive -- some artifacts were used as both toys and ritual objects.

The distinction between those two terms is not necessarily as clear-cut as it seems, because toys are often incoporated into ritual contexts (as offerings or grave goods, for example) and they can also be used to familiarize children with rituals and religious beliefs.

Regardless of why they were made, they are strikingly adorable.

Life-Sized Mortuary Doll from Siberia, c.250 CE: a small pouch filled with cremated human remains was tucked into the body of this mannequin, which was then stuffed with grass, dressed in furs, and buried

The mannequin measures about 1.5 meters (nearly 5 feet) tall, and it was crafted out of leather, fur, woollen fabric, tendon thread, silk, and grass. This is one of several mortuary dolls that have been found at the burial complex known as Oglakhty cemetery, which is located in the Oglakhty mountains of southern Siberia.

The mannequin's face was created from a patch of red woollen fabric; a rolled-up piece of leather was tucked beneath that patch in order to create the shape of the nose, while leather flaps were used to form the ears. Several black lines were also drawn across the face using charcoal.

The mannequin was positioned with its head resting atop a leather cushion filled with grass and reindeer fur.

Oglakhty cemetery is associated with the Tashtyk culture of southern Siberia. This article describes their unique burial practices, which often included a mix of mummification and cremation rituals:

The communities belonging to this group left numerous burial sites with an expressive funeral rite famous for its tradition of funeral masks and ‘dummies’: leather-made models of human bodies up to 1.5m in length, stuffed with grass, and  containing charred human bones.

Of special interest is the fact that different rites were used to bury individuals in the same grave: the mummies and dummies both contained human bones. Remains of the mummies, i.e. dry bodies with trepanned skulls and faces covered with gypsum masks were lying side by side with the dummies.

And as this article notes:

These mannequins or so-called ‘dolls’ are the only surviving examples of burials of this type.

It's believed that the mannequins are dressed in clothing that was originally worn by the dead people they represent. Some of the mannequins also have plaits of human hair that were likely taken from the dead just prior to cremation; the hair was then used to form neatly-braided hairpieces that were typically placed upon the mannequins' heads.

Many of the graves at Oglakhty cemetery exhibit a peculiar mix of both inhumation and cremation. That blend of rituals is often attributed to the arrival of peoples/traditions from other regions, and the cultural diffusion that gradually occurred as a result:

Different ways of burying people in the same graves in the early Tashtyk cemeteries may reflect their different origins: descendants of local population and immigrants living and buried alongside each other.

This is Jinx: my brother found her after she was abandoned at a local park, but he scooped her up and brought her home; she has a neurological disorder that impairs her ability to walk properly, and thanks to a birth defect, she doesn't have any teeth

In addition to the neurological disorder and the dental defect, Jinx also has some minor deformities in one of her eyes, her tail is kinked, she's a runt, and she apparently had a botched spay procedure at some point in her life. She's mostly just heart-stoppingly adorable, though.

Here is a video of her trying to be ferocious:

My brother brought her home about three years ago, after he found her sitting in the parking lot of a local park. When he first approached her, she tried to run away, but she immediately fell over and then struggled to get back up again. My brother just assumed that she was injured, so he scooped her up and carried her back home.

When we took her to the vet, we learned that she wasn't injured, but that her balance issues are likely the result of a disorder known as cerebellar hypoplasia (CH), which is sometimes referred to as "wobbly cat syndrome." It's a developmental disorder in which the cerebellum (the part of the brain that controls movement and balance) fails to develop properly in utero. The disorder affects her ability to stand, walk, jump, etc.

Cats with CH can have mild, moderate, or severe disabilities, but Jinx's impairments are on the mild/moderate side of that scale -- she can walk, but she is very uncoordinated, and she frequently staggers, sways, or tips over, especially when she's startled or in distress. She then has a lot of trouble regaining control of her limbs and getting back up again, which sort of makes her look like a "fainting goat." It's hard for her to keep her head steady, so she repeatedly "bops" her nose against anything that she's trying to sniff or eat.

The bobbing motion means that she is a very messy eater, and that issue is made even worse by the fact that she doesn't have any teeth and she generally forgets to close her mouth. Her toothlessness is the result of another congenital defect known as oligodontia, meaning that her teeth failed to develop, aside from a couple of tiny, mishapen "toothlets" near the front of her mouth.

She also seems to have had a botched spay procedure at some point, because there's evidence that another vet attempted to spay her (and she has the scar to prove it) but she still goes into heat at erratic intervals, and it seems to cause her much more distress than you'd normally see in a healthy cat. Our veterinarian suspects that the person who performed her surgery accidentally left behind some of the ovarian tissue, thereby wreaking havoc on her hormones.

Given the circumstances, we're pretty sure that someone deliberately abandoned her. The lot in which she was found is located in the middle of a very large park, and it's surrounded by several acres of pine forest, densely packed thickets, thorns, tall grass, and muddy terrain. Given her mobility issues, there's no way that she could have traversed all of those obstacles on her own, especially not without getting at least a little bit disheveled and dirty, but her fur was still clean and well-groomed when we found her...which means that someone must have driven her there and then left.

She's an absolute sweetheart, though. She has some peculiar habits, but she is still incredibly affectionate. She literally comes running to greet me every time I open my bedroom door, and she does the same thing with my brother.

She always sleeps next to my Dad at night, too, and as soon as he goes to bed, she follows him in and says "goodnight" to him by snuggling up to his neck, kneading his shoulder, and kissing his face (tho her kisses are kind of messy, because the toothlessness means that she drools a lot and almost always leaves her mouth hanging open).

Edit: Jinx was diagnosed with CH, but there's a possibility that her symptoms are the result of a congenital vestibular dysfunction instead, because both disorders are known to cause issues with balance, movement, and posture, but she has some symptoms that are more closely associated with CH, and others that are more closely associated with vestibular disorders. CH is still the likelier culprit, tho.

Moss-and-Lichen Katydid: these katydids are covered in cryptic markings and textures that allow them to blend in with their mossy, lichen-covered habitat, and their wings even mimic the appearance of a twig

The katydids of this genus (Anaphidna) can be found in the rainforests of Central and South America. They have cryptic features that mimic the mossy, lichen-covered environments in which they live -- their bodies are covered in green, brown, and white markings that are accented by bumpy, moss-like features, and their long, slender wings are usually held upward at a 45-degree angle in order to mimic the shape of a twig.

As this article notes:

These katydids fly well and probably live in the canopy, perhaps on trunks and mossy branches, where the camouflage should be particularly effective.

The moss-and-lichen mimic katydids of the group treated here are easily recognized by their long and slender wings held upward at an almost 45-degree angle. They live in rainforests of central and northern South America, with one species ranging southward to subtropical forest in NE Argentina.

Giant Antlions (Palpares immensus): these enormous antlions have been known to attack geckos and other small reptiles

The images above depict the larval stage of Palpares immensus, which is one of the largest antlion species in the world.

This article provides more information about the unusual behavior of this species:

The larvae live freely in sand and are ambush hunters. They are voracious predators and feed mainly on other arthropods, but have been known to attack geckos and, in one case a small adder. They are unable to feed on these reptiles and usually die as a result of not being able to extract their jaws from the vertebrate prey.

These antlions can be found in sandy, arid environments throughout southern Africa.

The adult form of Palpares immensus is also depicted in the images below:

Palmetto Tortoise Beetle: the larvae of this species produce long, thin strands of feces that are gradually woven together to form protective "fecal shields" around their bodies

During its larval stage, the Palmetto tortoise beetle (Hemisphaerota cyanea) uses its own feces to create a defensive layer known as a "fecal shield" or "fecal thatch."

As this article explains:

Most remarkable, perhaps, is the fecal “thatch” of Hemisphaerota cyanea. In the larva of this beetle, the feces are emitted in strands, which, as they build up over the course of larval life, form a loose assemblage that totally hides the larva from view.

The construction of the "fecal thatch" begins almost immediately after the larva hatches. Each larva begins to feed within minutes of hatching, and the very first fecal strands emerge from its anal turret just a few minutes later. Subsequent strands are then produced in quick succession, and they begin to accumulate around the larva's body; as each strand emerges, it is made to curve around the larva's left or right side depending on whether the anal turret is flexed to the left or right. The direction of the curve usually alternates from one strand to the next, ensuring that a nest-like structure is formed around the larva's body.

As they emerge, the fecal strands are gathered together and then cemented into place with the help of an anatomical feature known as a caudal fork. Once an individual strand has been extruded to its full length, the anal turret is rotated upward until it comes into contact with the caudal fork, and the larva then pinches off the strand while secreting a droplet of "glue," which effectively cements each fecal strand into place against the caudal fork.

It generally takes about 12 hours for the larva to finish building its very own "fecal shield."

As an adult, the Palmetto tortoise beetle has another unusual defense mechanism: its tarsi (i.e. feet) are each lined with 10,000 tiny adhesive bristles, and when the beetle is attacked, it can press its feet flat against the surface of a leaf and secrete an oil that allows it to adhere to that surface with an enormous amount of strength. The adhesive mechanism is strong enough to resist pulling forces that are up to 60 times greater than the beetle's own weight for a full 2 minutes; it can resist even greater forces (up to 230 times greater than the beetle's own weight) for shorter periods of time.

According to this article from the University of Florida:

Each of the greatly enlarged tarsi is equipped with approximately 10,000 adhesive bristles. Each bristle has two terminal pads. When walking, only a few of the bristles touch the leaf surface. However, when attacked by a predator, the beetle puts all or nearly all of the bristles in contact with the surface and secretes oil onto the pads. With the adhesive force created by the oil between the leaf surface and tarsi, the beetle is able to clamp its hemispherical shell down tightly against the leaf and has been demonstrated to withstand pulling forces of approximately 60 times its own weight for up to two minutes. This time period is sufficient to thwart the efforts of predatory ants attempting to pry the beetle from the leaf. 

Palmetto tortoise beetles are native to the southeastern United States, and they're especially common in Florida (which is why they're also known as Florida tortoise beetles).

African Woolly Chafers (Genus Sparrmannia): these beetles have a uniquely "fluffy" appearance, thanks to the long, fur-like setae that covers their bodies

Beetles of the genus Sparrmannia are widely distributed throughout the arid regions of southern Africa. They have very distinctive features, with large, plump bodies and tawny-colored "fur," and some species can measure up to 25mm (nearly 1 inch) long.

They generally hide in underground burrows during the day, and emerge only at night, when the desert is substantially cooler. The dense layer of "fur" acts as insulation, which allows the beetles to remain active at night, even when the temperatures plummet.

"Zeugma Mars" Statue from Turkey, c.250 CE: this statue depicting Mars, the Roman god of war, was unearthed from the ruins of a city that was occupied and plundered by the Sassanids in 253 CE

The bronze figure is nearly 1.5 meters (5 feet) tall. It has a strikingly intense expression, with eyes that are highlighted by gold and silver inlays.

According to this article:

A bronze statue of Mars, the Roman god of war, was found in the ancient city of Zeugma in the course of an excavation campaign in 1999-2000. The statue represents one of the most interesting and spectacular finds from this city on the banks of the Euphrates river in southern Anatolia.

The statue is of great interest on one side for its rarity, as few Roman bronzes of such size are so well preserved, and on the other for its unusual iconography, depicting the standing God as a young athlete. The figure stands with the weight centered on the right leg, while the left, slightly bent, rests only on the flexed toes. The right arm is raised, its hand closed around a spear that has not been found, while the left is bent at the elbow, to almost 90° and with the hand wielding an object that appears to be a scourge with multiple and symmetrical endings.

Beneath the helmet, thick curls frame the face of the young man whose frown is marked by strongly furrowed eyebrows and a very intense gaze, highlighted by silver and gold inlays around the pupils.

A chandelier was found along with the bronze. It is composed of a drum, similar in length to the sculpture, which passes through a disc and is inserted in a base. The small size of the space in which the artifacts were discovered and its place in the general plan of the villa suggests a closet where the precious materials were hidden to escape the pillaging of the city, carried out in 253-6 AD by the Sassanids.

Giant Emerald Pill-Millipede: when these enormous millipedes are all rolled up, their bodies can be as big as a baseball, a tennis ball, or a small orange

This species (Zoosphaerium neptunus) is commonly known as a giant emerald pill-millipede. The females can measure up to 90mm long (roughly 3.5 inches), making this the largest species of pill-millipede in the world.

There is a significant degree of sexual dimorphism in this species, with the males measuring only about 45mm (1.8 inches) long -- roughly half the size of the females.

Giant emerald pill-millipedes are found only in Madagascar, which is home to several endemic species of giant pill-millipedes (order Sphaerotheriida). The Malagasy name for giant pill-millipedes is "Tainkintana," which means "shooting-star."

Pill-millipedes use conglobation as a defense mechanism, which means that they can curl their bodies up into a spherical shape so that their dorsal plates form a protective shield around the softer, more vulnerable parts of their bodies, just like an actual pill-bug or a "roly-poly."

When they roll themselves up completely, they look almost like gently polished chunks of malachite, emerald, or jade.

Giant emerald pill-millipedes will sometimes form large swarms that travel together as a group. This is the only species of giant pill-millipede that engages in any sort of swarming behavior, and the purpose of that behavior is still unclear. The swarms often contain thousands of individuals, with almost all of them moving in the same direction, even when there is no physical contact that might allow the millipedes to "herd" one another along.

Their swarming behavior also has some very peculiar features, as this article explains:

During swarming, Zoosphaerium neptunus individuals pay little attention to their surroundings; many specimens were observed walking straight into and drowning in small puddles. Some swarms even display ‘cliché lemming behaviour:' in Marojejy, a large part of a swarm walked into and drowned in a small river.

No single specimen was observed walking ‘against the current,' all specimens were moving in the same direction (southeast), even when not in contact with one another.

Of 273 randomly collected individuals, 105 were males, while 168 were females. The males were 8.3 - 14.1 mm wide (average width 10.4 mm). According to the inner horns of the posterior telopods, all males were sexually mature. The females were 9.95 - 15.4 mm wide (average width 11.4 mm). All females displayed non sclerotized vulvae and were sexually immature.

Some researchers argue that the swarming serves as a defense mechanism, providing a layer of protection (or at least some cryptic cover) against local predators, but the swarming behavior is still poorly understood.

Important Note: I just want to remind everyone that these animals belong in their own natural habitat -- they should not be trapped, bought/sold, traded, shipped, collected, or kept as pets. This particular species does not survive well in captivity, either, and the demand for these "exotic" invertebrates is putting the wild populations in jeopardy. The previous article discusses those issues, too:

Another possible threat for Z. neptunus swarms are collections for the pet trade. There exists a large demand in Japan, Europe and North America for 'green -eyed monsters’ as pets. Giant pill -millipedes from Madagascar unfortunately have a very short survival time in terraria. The species is specialized on low-energy food (dead leaves), and adapted to the cool climates (<20°C) of the highlands. Specimens in terraria often starve to death quickly.

So I know that they're adorable and really, really fascinating...but let's just let them be their chunky, adorable little selves out in the wild where they belong.

Ram's Head Pendant from the Eastern Mediterranean, c.500-300 BCE: this adorable glass pendant was made nearly 2,500 years ago

The pendant measures about 2.22 cm (7/8ths of an inch) across, and it depicts a ram's head, with a pair of twisting, caramel-colored horns framing its face.

According to The Walters Art Museum:

Miniature glass pendants in a large variety of colors and shapes can be found all over the Mediterranean world and were probably produced in several glassmaking centers, including Carthage, Iran, and Syria. These objects were distributed through the expansive, widespread trade routes established by the Phoenicians. Rams were considered fertility symbols, and this pendant likely also had a protective function and was intended to ward off evil.

And the Smithsonian adds:

Small amulets made of faience, stone, ceramic, metal, or glass were common personal possessions in ancient Egypt. They were most frequently fashioned in the form of gods and goddesses or of animals sacred to them. Amulets were believed to give their owners magical protection from a wide variety of ills and evil forces, including sickness, infertility, and death in childbirth. They were often provided with loops so they could be strung and worn as a necklace. Some amulets were made to place on the body of the deceased to protect the soul in the hereafter.

There is evidence to support those explanations, of course, but I always feel the need to point out that some ancient artifacts were also made for reasons other than practical or ritualistic/spiritual purposes -- sometimes they were just decorative or artistic. These particular pendants may or may not have had any spiritual significance...but either way, they're adorable.

"Ram in the Thicket" Statuette from Ur (Iraq), c.2600-2400 BCE: this statuette is made of lapis lazuli, shells, gold, silver, limestone, copper, and wood

This sculpture is about 4,500 years old. It was unearthed back in 1929, during the excavation of the "Great Death Pit" at the Royal Cemetery of Ur, located in what was once the heart of Mesopotamia (and is now part of southern Iraq).

Sir Leonard Woolley, who led the excavations at the site, nicknamed the statuette "ram caught in a thicket" as a reference to the Biblical story in which Abraham sacrifices a ram that he finds caught in a thicket. The statuette is still commonly known by that name, even though it actually depicts a markhor goat feeding on the leaves of a flowering tree/shrub. Some scholars refer to it as a "rampant he-goat" or "rearing goat," instead.

It was carved from a wooden core; gold foil was then carefully hammered onto the surface of the goat's face and legs, and its belly was coated in silver paint. Intricately carved pieces of shell and lapis lazuli were layered onto the goat's body in order to form the fleece. Lapis lazuli was also used to create the goat's eyes, horns, and beard, while its ears were crafted out of copper.

The tree (along with its delicate branches and eight-petaled flowers) was also carved from a wooden base, before being wrapped in gold foil.

The goat and the tree are both attached to a small pedestal, which is decorated with silver paint and tiny mosaic tiles made of shell, lapis lazuli, and red limestone.

This artifact measures 42.5cm (roughly 16 inches) tall.

A second, nearly-identical statuette was also found nearby. That second sculpture (which is also known as the "ram in the thicket") is pictured below:

There are a few minor differences between the two sculptures. The second "ram" is equipped with gold-covered genitals, for example, while the first one has no genitals at all; researchers believe that the other sculpture originally had genitals that were made out of silver, but that they eventually corroded away, just like the rest of the silver on its body.

The second "ram" is also slightly larger than the first, measuring 45.7cm (18 in) tall.

Both statuettes have a cylindrical socket rising from the goats' shoulders, suggesting that these sculptures were originally used as supports for another object (possibly a bowl or tray).

The depiction of a goat rearing up against a tree/shrub is a common motif in ancient Near Eastern art, but few examples are as stunning (or as elaborate) as these two statuettes.

2,300-year-old Horse Headdress from Siberia, c.350-250 BCE: this ceremonial headdress/mask was found on the body of a horse that had been buried in the frozen tombs of Pazyryk

The elaborate headdress features a pair of "antlers" that were crafted from wood, leather, fur, and dyed horsehair, with a mask made of blue-colored felt and gold foil. This is just one part of a larger ceremonial costume that was made by Scythians/Altaic nomads. It was found in the Pazyryk barrows, located in the Altai mountains of Siberia, where many other Scythian artifacts have been preserved in the permafrost.

The term "Scythian" refers to the nomadic cultures that once roamed across Eurasia. The Scythians were among the very first people to begin using horses as mounts, and they invented the earliest form of saddle; with their mastery of horseback riding and mounted warfare, the Scythians quickly gained control over vast sections of Eurasia. Their nomadic lifestyle also meant that they were deeply dependent upon their horses, and many traditions and beliefs were developed around that relationship, ultimately giving rise to a very prominent "horse culture."

Scythian warriors were often buried alongside their horses, which would be dressed in elaborate ceremonial costumes that included special masks, headdresses, antlers or horns, decorative bridles, harnesses, and/or saddle covers.

Few of those costumes were as elaborate as this one, however.

Above: a full reconstruction of the costume that was found with the headdress

This particular costume (and the horse that was wearing it) was found in a tomb that also contained the bodies of nine other horses; all of them had been buried with ceremonial bridles, harnesses, and saddle blankets, but this horse had the most elaborate costume by far, and it was the only horse that was actually wearing its costume when it was buried.

It was also the oldest horse at the burial site, with researchers estimating that it was about 20 years old when it died. The second-oldest horse (which was about 18 years old) was also buried with a costume that included an elaborate headdress and horns/antlers. Those features were not found on any of the younger horses, however.

As this article notes:

At Pazyryk-1, the size and complexity of each horse’s saddle decorations were generally correlated with age; the horses who wore the most elaborate costumes with headdresses were the oldest.

It is clear the costumes were not made specifically for the burial: all horse costumes, even the most elaborate, were well-worn and in some places mended, indicating regular use. Because these costumes are impractical for everyday use, they probably were reserved for ceremonial use – and due to their being well-worn, such use was common. As with contemporary Mongol pastoralists, perhaps these costumes were reserved for the Pazyryk’s seasonal changes of camp, or perhaps for other alternate or additional ceremonies significant to the community.

The Common Whistling Moth: the males of this species produce a "whistling" sound to attract potential mates

The common whistling moth (Hecatesia fenestrata) is able to "whistle" with a set of castanet-like structures located on the leading edges of the forewings.

Above: the forewing of a male whistling moth, with the transparent "castanet" structure clearly visible

These unique structures are basically just curved, transparent patches of cuticle with a pleated/ridged texture and a knob-like protrusion; when the moth claps its wings together, the knob-like protrusion from one wing rubs up against the cuticle ridges on the opposite wing, and a distinctive "clicking-whistling" sound is produced.

Male whistling moths typically "whistle" during courtship rituals and territorial displays. In some cases, they will fly in circles around one another as they whistle competitively, in a behavior known as "buzz-bumping." As this article explains:

Only a few [noctuid moth species] have proved to use sound during courtship. Among these are males of the Australian whistling moths Hecatesia exultans, H. fenestrata and H. thyridion.

The signals function primarily in a mate-attraction mode. Females approach calling males and solicit copulations. The mating system of Hecatesia appears to be an example of lek polygyny. Males defend territories that lack resources or oviposition sites.

Above: female whistling moth

Male–male agonistic interactions are also mediated by acoustic signals. Males frequently approach males calling nearby, and territorial ‘buzz-bumping’ matches result in which vigorous calls are interspersed with attempts to butt the intruder.

H. thyridion and H. fenestrata have similar acoustically mediated mating systems. Males in these species call during special upwind zigzagging display flights over their territories. Instead of ‘buzz-bumping,’ territorial males participate in buzzing aerial ‘dogfights’ with intruding males.

The genus Hecatesia contains several different species of "whistling moth," all of which are endemic to Australia. Each species produces its own unique whistle; the exact social context/role of that behavior also differs slightly from one species to the next.
