Wet Beast Wednesday: aquatic insect larvae
This Wet Beast Wednesday is going to be different than usual. Instead of an in-depth overview of a specific species or group of species, I'm going to give a general overview of aquatic insect larvae as a whole and then showcase some groups of insects. I'm going to focus on insects that have an aquatic larval stage and terrestrial adult stage, saving adult aquatic insects for another post.
Tumblr media
(Image ID: a group of mosquito larvae. They are yellowish bugs with long, slender bodies, no visible limbs, small heads, and feathery appendages from their rear ends. From the back of the abdomen, a snorkel-like appeadage attaches to the surface of the water, using surface tension to allow the larvae to hang from the surface. End ID)
Insects are basically the most successful group of animals in the history of life on Earth and have adapted to live in just about every terrestrial habitat. It should not be much of a surprise than that they have also moved into the water. More specifically, fresh water as almost all aquatic insects inhabit fresh or maybe brackish water. Only the water strider genus Halobates are truly marine. Some species of insect are aquatic for their entire lives, some are primarily terrestrial but able to swim, and some are aquatic only for their larval stage of life. These aquatic larvae species are generally agreed to have evolved from fully terrestrial ancestors. The adaptation of partially returning to the water has evolved independently many times in many different clades of insect and so different species use different strategies and adaptations. It is possible that aquatic larvae evolved in response to high competition for resources on land. If multiple species are competing over the same resources during their larval stages but one of those species manages to adapt to a whole new environment, that species will now have abundant access to resources the other species are unable to get to. Because of the very different lifestyles required for aquatic and terrestrial animals, aquatic larvae often look very different than their adult forms.
Tumblr media
(Image: an aquatic beetle larva. It looks nothing like an adult beetle, instead being a long, slender insect with no wings, multiple body segments, and two hairy appendages at the base of the abdomen. End ID)
Aquatic larvae serve important roles in their ecosystems. Many are herbivores or detritivores that consume algae and bits of biological material, helping recycle nutrients and clean the water. Some are predators that hunt smaller invertebrates or plankton. Importantly, aquatic insect larvae provide a major food source for larger fish, invertebrates, birds, and so on. Some species can be considered keystone species, vital to their ecosystems. Many species are highly sensitive to changes in their environment, allowing them to act as indicator species for the health of their ecosystems. The trio of mayflies, stoneflies, and caddisflies are very commonly used as indicators of pollution as all three are highly sensitive to pollutants. A stream with few mayflies, stoneflies, or caddisflies but plenty of less sensitive species is likely to be polluted.
Tumblr media
(Image ID: a collage of aquatic larvae of multiple species in the order Diptera (true flies. They vary from slug-like to having multiple distinct body segments with legs, to looking like maggots with long tails. End ID. Source)
Mayflies (order Ephemeroptera) are among the oldest lineages of winged insects, bearing traits that they first flying insect also had. Juvenile mayflies are technically not larvae, but nymphs. The difference between a larva and a nymph is that nymphs look much more like the adult stage than larvae do. Mayfly nymphs lack the wings of adults, but have external gills growing from the sides of their abdomens. Mayfly nymphs can be identified by three appendages called cerci that emerge from the back of the abdomen. They are bottom-dwellers that typically live under rocks and other objects or amid plants. Most are herbivores, feeding mainly on algae. Months to years after hatching (species dependent), mayflies will float to the surface and go through a molt to a stage called the subimago. Uniquely among insects, mayflies go through two final winged molts. The first is to a not sexually mature stage called the subimago, then they quickly molt again into a fully mature imago stage. These molts happen in sync, resulting in hundreds to thousands of mayflies appearing all at once and swarming together to mate. Famously, adult mayflies exist only to mate and die. Their digestive systems are non-functional and few species last past a few days.
Tumblr media
(Image: a mayfly nymph on a rock. It is a yellow bug with no wings, a long abdomen, and thick, grasping legs. Three long, hairy cerci emerge from the back. Along the side of the abdomen are multiple pairs of white, feathery gills. End ID)
Stoneflies (order Plecoptera) also have nymphs and can be quite difficult to tell apart from mayfly nymphs if you don't know what to look for. One of the biggest differences is that their gills are located by the base of the legs rather than along the abdomen. Like mayflies, stoneflies are some of the most primitive winged insects, but mayflies are Paleopterans (the earliest wings insects) while stoneflies and most other winged insects are Neopterans. The main difference is that Neopterans can flex their wings over their abdomens while Paleopterans cannot, and must hold their wings either out to the side or up in the air. Like with Mayflies, many adult stoneflies have nonfunctional digestive systems and exist only to mate and die.
Tumblr media
(Image: a stonefly larva. It looks similar to a mayfly larva, but has a shorter abdomen, gills along the base of the legs, and only two cerci. End ID)
Caddisflies (order tricoptera) are the builders of the aquatic insect world. These larvae (most species anyway) can produce silk from glands near their mouths. These are used to make a variety of structures made from silk and various other materials including sand, silt, plant parts, shells, rock, and so on. Different species will seek out specific materials for their structures. There are a few types of structures, the most common of which is a tubular case that is open at both ends. The larva can carry the case with it as it crawls around and can retreat into the case for protection. The larva can draw water into one end of the case and out the other, allowing oxygenated water to flow over the gills. By moving around in the case, the larva can draw in more water. This allows the larvae to survive in water that is too oxygen-poor for other larvae. Other species build different structures including turtle-shell like domes or stationary retreats. My favorite structures are nets built with an open end into current. The current naturally brings detritus and micro-invertebrates into the net, where the larva can eat them. Caddisflies also pupate into pupa that have mandibles to cut their way out of their cases and swimming legs. Once developed, the pupae swim to the surface and molt into their adult forms. This molting is synchronized to ensure the adults emerge in swarms and can easily find mates.
Tumblr media
(Image ID: a caddisfly larva in its case. The case is a tube composed of pebbles of different colors stuck together with silk. The head and legs of the larva are merging from the front of the case. End ID)
Tumblr media
(Image: a caddisfly net. It is a structure made of silk shaped like a tube that is wide at one end and tapers toward the other. It is curved so both ends face the same way. End ID)
The order Megaloptera consists of alderflies, dobsonflies, and fishflies. All three have aquatic larvae, but their eggs are laid on land. Most species lad their eggs on plants overhanging the water so the larvae fall in once hatched, though a few lay eggs near the water's edge, forcing the larvae to crawl in. Meglaoptera have the least amount of differences between larva and adult of all holometabolous (pupa-forming) insects. The largest differences between the larvae and adults is the larvae lack wings and some species have leg-like prolegs. All species are carnivorous as larvae and feed on other invertebrates.
Tumblr media
The adults don't look any less creepy
(Image: two hellgrammites, the larval form of a dobsonfly. It looks somewhat like a centipede with three pairs of limbs and a long abdomen with multiple pairs of leg-like prolegs. The head has no visible antennae, but does have a pair of powerful pincers. End ID)
Order Odonata consists of dragonflies and damselflies. These are powerful predators both as nymphs and adults. As nymphs, the juveniles are shorter and stockier than the adults, with no wings. The nymphs (or naiads) breathe through gills. In damselflies, these gills can be external, but dragonfly nymphs have their gills located in the anus. Damselflies can swim by undulating their gills, but dragonfly nymphs are restricted to crawling. The nymphs are voracious predators that will feed on anything they can catch. Most of their diet consists of invertebrates, but they will also attack small fish, tadpoles, and even salamanders.
Tumblr media
(Image ID: a dragonfly larva on a rock. Its head is similar to that of the adults, but the abdomen is much shorter and broader and the legs are longer. It has no wings and is brown all over. End ID)
The groups of insects I covered today (plus the stoneflies) all have exclusively or near-exclusively have aquatic larvae while the adults are terrestrial. In other groups, aquatic larvae may be present in some species while others have terrestrial larvae. For example, a great many members of the order Diptera (true flies) have aquatic larvae including all mosquitos, while other members of the order have fully terrestrial larvae. In addition there are species of beetle (order Coleoptera), moth (order Lepidoptera), lacewing (order Neuroptera), and scorpionflies (order Mecoptera) that have aquatic larvae and some species of the true bugs (order Hemiptera) have aquatic larvae and aquatic adults, including water skaters, water scorpions, and giant water bugs. Aquatic insects are so prevalent that it is rare to find any lasting body of water that doesn't host some aquatic larvae or adults. Even incredibly stagnant and filthy water can host aquatic insect larvae, as shown by the notorious rat-tailed maggots, who love stagnant water and breathe through snorkels. Many species require very specific conditions and there are species of insect who exclusively grow their larvae in specific streams or lakes. Because of this, conservation of these bodies of water is vital to their survival and pollution, damming, and other factors can destroy whole species.

I know the anime was generally conceived as bad so the topic is probably soured in most people’s minds but the “pupa” manga was honestly so fire, dream-like, creepy and ethereal and I think darkshippers would honestly like it if y’all read it

Ant pupae in a nest I had to disturb last year during trail cleanup. Lucky for them, the adults were hard at work relocating them to safety.

made a quick visual of the BDFB life cycle for my experimental design class project. figured it looked nice enough to share here ^^
there's only four stages (egg -> larva -> pupa -> adult), but i decided to make the graphic with more detail bc it's relevant to my project :-)

The weirdest trip I have ever been on and I enjoyed it, despite that I wouldn’t recommend it, unless you enjoy this kind of weirdness.  The plot is all over the place, you would be so confused in the end of it all. Nonetheless it most watch just to see at least once no matter how bad it is.  for those who are into weird  enjoy the ride.

The Common Green Lacewing: these tiny insects pupate within loosely-woven cocoons that measure just 3-6mm (about 1/8 to 1/4 inch) in diameter
Tumblr media
The lacewing will spend about 5 days maturing within its cacoon, before it cuts an opening in the top and emerges as a fully-developed adult.
Tumblr media
The larvae of the green lacewing (family Chrysopidae) are also known as "aphid lions," due to their skill/appetite when it comes to hunting aphids. They're widely used in agricultural contexts to help eradicate pests, because they are voracious predators that also commonly prey upon caterpillars, leafhoppers, planthoppers, thrips, spiders, mites, and insect eggs.
As it nears the end of its larval stage, a lacewing will spin a small cacoon out of silk and then tuck itself inside, allowing the pupal phase to begin; its tiny green body is often partially visible through the thin, loosely-woven walls of the cacoon.
These breathtaking photos of a lacewing climbing out of its cacoon were taken by a Danish photographer named Frederik Leck Fischer.
Tumblr media
When a lacewing first emerges from a cacoon, its wings are still compactly folded down against its body; the wings then gradually begin to expand until they have reached their full size, which usually takes about an hour or two.
Tumblr media
Fischer's photographs provide an excellent account of this entire process.
Tumblr media
Here are just a few other images of the common green lacewing:

SOOOO GOOD#this isn’t a very In Depth discussion of my thoughts sorry i need to spend more time in this seasons nooks and crannies#ooh ohh and the replicants this season were so cute too. THEY GREW TOGETHERRR#i liked the shlorp lore and little peeks into their past too#anyways i got sidetracked yeah amazing season#I FORGOT TO MENTION THE ANIMATION#THE ANIMATION THIS SEASON WAS BONKERS DUDE. LOVED HOW FLUID IT WAS AND ALL THE FUN NEW EXPRESSIONS THE SOLARS HAD#THAT SCENE OF THEM SAYING DEENOSAUR WAS LIKE MY FAVORITE EXAMPLE#gonna keep adding as i remember things im glad they wanted to explore jesses character more#but i dont like how they jeopardized korvos character for them to get there#kinda made him backtrack his progress for the sake of that episode :/ just a really big shift i wasnt a fan of#and they didnt make him feel remorse that whole episode either he didnt even say sorry :/#also terry was just chill with chris that whole episode? have we just moved past the hall of betrayals thing?#i guess jesse’s roast about him being sky blue really just set him off for the rest of the season#he needs to talk to someone professional#i feel like solars is a really weird blend of being umm.
