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
Tumblr media
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.

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.

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.

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.

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.

Honestly, I love it when characters relapse. When someone who’s gotten over their anger issues falls into a situation so out of their depth they fall back on their old habits. When someone who’s learned to open up becomes a recluse again in order to cope with something outside their control.
There’s just something so horrible, so toxic, about watching a character grow and then slip back into their old selves in order to cope, bc you know they still care, that they’re the same inside, but watching them hurt so hard they don’t know what else to do brings a sense of catharsis.

I love how full of shit Kyoko is. How she tries to appear selfish and cool and unbothered but is so kind and actually desperately wants to believe in people and in goodness again. "Oh yeah, I live for myself and think fighting for justice is naive haha" girl what are you talking about. The two people who help define your arc have hero complexes. And you sacrificed so much for both of them. You became a magical girl for one of them and died for the other. Your soul gem is placed on your chest, where your heart is. If this was a normal teenage drama you would be that kid who tries desperately to act edgy but feeds puppies and kittens after school.

It's time for Trilobite Tuesday! Trilobites were among the first animals to develop the ability to enroll for protection. With their thick calcite shells, an enrolled trilobite could present quite the daunting challenge for any predator seeking an easy meal. Scientists think trilobites first started using this defensive position some 520 million years ago, during the Lower Cambrian. By the time Dipleura (pictured) inhabited the primal seas during the Devonian, trilobites had long-since mastered this art of rolling up into spherical “balls.” This specimen, found in Pennsylvania, is nearly 3 in (7.6 cm) in diameter.

"It's strange that they don't seem to mind you, Otto," he said, calming down a little.
"Vell, I am not official," said Otto. "I do not haf zer sword und zer badge. I do not threaten. I am just a vorking stiff. And I make zem laff."
Vimes stared at the man. He'd never thought about that before. But yes...little fussy Otto, in his red-lined black opera cloak with pockets for all his gear, his shiny black dress shoes, his carefully cut widow's peak and, not least, his ridiculous accent that grew thicker or thinner depending on whom he was talking to, did not look like a threat. He looked funny, a joke, a music-hall vampire. It had never previously occurred to Vimes that, just possibly, the joke was on other people. Make them laugh, and they're not afraid.

i like to think that telemachus inherited none of his father's smooth-talking wit and none of his mother's intelligence. instead what he inherited from penelope is her kind heart and gentle demeanour and what he got from odysseus was orange cat brand of stupid, resulting in telemachus being this boyfailure ball of anxiety with a heart of gold and braincells that are only intelligent in the direst of situations

Ah yes, Jean Moreau. King of Insults.
The same Jean who learnt english as a third language and hardly spoke anyone outside of the ravens.
The same Jean that probably crafted his insults from things he’s heard the Ravens say, things that were said to him.
Feckless Tedious Wrench
I mean his go-to insult is to call someone a child and to the Ravens he was the child.
Do you get my point?

Everything Is Meant (long S2 analysis, part 3)
Part one
Part two
There's SO MUCH excellent meta out there right now, and I'm going to try not to reinvent the wheel too much, but I want to keep going with tying the episodes/ elements up together because on first watch it wasn't entirely clear how everything fit. I also strongly recommend a rewatch, no matter what you felt about the ending... if you need to stop it 10 minutes early, do that, but you pick up so much more the second time around.
So: Maggie and Nina. I spent most of my first watch wondering why we were bothering with them, honestly. Later in the season Nina, and then Maggie and Nina, gave Crowley some insightful advice, but their actual relationship didn't progress despite all the meddling, and the amount of emotional investment BOTH Aziraphale and Crowley had in making them get together was frankly strange.
I started thinking in terms of mirror couples, since that was such a big deal in S1 and that's clearly what they were set up to be, but I made the mistake that all of us made on first watch: that Nina was Crowley and Maggie was Aziraphale. It still wasn't really coming together.
Then I put the psych hat back on and started to think about displacement. Displacement is a defense mechanism, and it consists of satisfying an impulse (usually an unconscious one) with a substitute object. At the beginning of the season, Aziraphale and Crowley aren't really in a good place, and I think on some level they know that. Aziraphale is trying to SHOW Crowley that he wants to take the next step through all the casual touches and phone calls and inviting him in, and feeling frustrated because Crowley doesn't seem to be taking the bait. (I absolutely think that Aziraphale tried to get Crowley to stay with him at the bookshop instead of living in his CAR, and Crowley said no. That's a whole other meta.) Meanwhile, Crowley, I think, is waiting for a Grand Gesture. Where did he go, as soon as Aziraphale brought up trying to get two humans to fall in love? Romantic tropes. Getting caught in the rain under an awning. A dramatic kiss that opens someone's eyes. That's the sort of thing he's always done, right? Big rescues, impassioned pleas on the street, fancy dinners, "give you a lift anywhere you want to go". He's defensive and guarded and unlikely to let someone in unless he's CERTAIN he won't be rejected, and Aziraphale's approaches are just too... quiet. No one's fault, they just don't speak the same language.
Then, they're handed the opportunity to make two humans fall in love, and they're both All In immediately. Look at Crowley's face when he summons the rainstorm. This is HUGE for him. Why? Because of displacement. Look at Aziraphale arranging the ball and being borderline deranged about it. They're both desperate to demonstrate what they think it takes for two people to move past their misunderstandings and fall in love. They can't do it for each other because the stakes are too high, and if either of them shows their cards unequivocally the vulnerability feels life-shattering. They're codependent and terrified of rejection and also, importantly, have no idea what they're doing when it comes to love. "Saw it in a film", Crowley says. Aziraphale's read about it in books. But they have zero practical experience.
Instead of learning to communicate, they try to say what they want to say through the medium of Maggie and Nina, up to and including the questionable moral decision to exert control over people's actions and thoughts during the ball. If I can just make this come out right, they both think, then things between us will be alright too. It HAS to come out right. They're attempting to gain some control over their own lives, over something that feels so overwhelming and shattering they can't look directly at it.
It doesn't come out right. Nina's relationship falls apart, but that doesn't mean she's in love with Maggie. While Crowley's stress-cleaning the bookshop to the music that played when Aziraphale got his books back in 1941 (just fuck me up David Arnold), they come in and tell him so. "I don't understand", says Crowley. Because it should have worked. Why didn't it work?
They tell him, of course. "You need to talk to each other. Say what you're really thinking." But here's the thing about communication: you have to learn it. You need to get the hang of expressing your feelings without blaming your partner, and separating intent from impact, and staying away from getting defensive and lashing out. No one has ever taught Aziraphale and Crowley how to do this. It's like Maggie and Nina put Crowley in front of a loom and asked him to recreate the Bayeux Tapestry. He doesn't have the skills; he's always going to get it wrong, even if he tries his hardest.
And he does try. But that's where Maggie and Nina the mirror couple, rather than Maggie and Nina the displacement relationship or Maggie and Nina the Greek chorus, come in. Aziraphale, as Nina, has just ended an incredibly toxic, invasive relationship with Heaven. A relationship that invaded every facet of his life, isolated him, and prevented him from being close to anyone else. "Rebound mess," Nina says. Aziraphale is a rebound mess. He's transferred the responsibility for his emotional wellness to Crowley. Crowley is the person he calls when he's in trouble, or (and this is key) when he wants to report a clever/ good thing he's done, or when he's bored. (At no point did Crowley reference Aziraphale calling him for a solicitous reason-- another problem.) Crowley is meant to take care of him. He forgets, I think, that Crowley is a person with his own wants and needs, just like Maggie and Nina are people with their own wants and needs who don't appreciate being messed with. (I think things would have been much different had Aziraphale BEEN THERE for Maggie and Nina's talk with Crowley, but he wasn't.)
And Maggie-as-Crowley? Lonely. Behind on rent, at risk of being evicted (it's important to note that Aziraphale saves Maggie from losing her record shop, as he couldn't save Crowley from losing his flat). Pining. Awkward. Revolving around Nina like a planet, to the extent that we don't get much of an impression of her otherwise. They realize, there at the end, that they both need to round themselves out before jumping into a relationship. Aziraphale and Crowley need that too. They need to take time apart and learn to be healthy on their own. Unfortunately they don't have the skills to get to that conclusion in a healthy way, so it all explodes in their faces and everything falls apart.
Aziraphale tries to teach Nina and Maggie to dance as a substitute for communication. Nina and Maggie try to teach Crowley communication as a substitute for the dance they've been doing around each other. That's the reason they're a part of the plot: they exist to demonstrate the way Aziraphale and Crowley might have succeeded in forging a better dynamic. Sadly, the boys' dance is too practiced and they got sucked right back into it.
It's okay, I think, that Nina and Maggie's storyline never really went anywhere. It wasn't supposed to. It's an allegory, not something that needs to stand alone.

There are three hyaenids found within the Imperial Wardi region- the hisippate, the highland hyena (kyniche na chennandi), and the scrub hyena (kyniche). (None are actually related to the king hyena).
The hisippate (name is close in meaning to 'stinking one', sometimes instead called '(wild) ant-dog' ('kulichin-wannaukoma')) is very distantly related to the other two. They are small, mostly solitary animals that sleep in burrows during the day and emerge to hunt at night. They are almost exclusively insectivorous, and their diet consists primarily of termites and ants that are lapped up with a long, strong tongue. The hisippate has a wide range, with their populations being highest in grassland and savanna regions with a high density of termites.
They are named for their foul smelling anal gland secretions, which are used to mark their territory and can be sprayed short distances to repel predators. Their highly visible black and white coat (which is erected in threat display) indicates them as not worth the trouble of eating. This is partly an honest advertisement of its chemical defenses, but may function as mimicry of a substantially more threatening native badger that can spray with great accuracy at distances of up to 10 feet (while the spray of the hitsippate is untargeted and only potent within a meter of the body).
The highland and scrub hyenas are the most numerous and successful predators within the region, with their populations having exploded in the past several centuries with the decline of the Wardi lion. Both live in matriarchal clan structures with strict dominance hierarchies, maintained not by individual size and strength but by highly complex networks of coalitions. All members of a clan can reproduce, and young inherit rank positions just beneath that of their mothers. Most males eventually disperse, entering into new clans at the very bottom of their hierarchy. They exhibit no obvious sexual dimorphism, and females often can only be differentiated from males by the shape of their pseudopenis.
The scrub hyena is most widely distributed and can be found throughout most of the region in a variety of lowland habitats, faring best in savannah and open grassland with high populations of grazing ungulates. This species is distinguished by well-defined spots and stripes and a sparse mane, though their coloration varies by individual and population, ranging from reddish to pale white-brown. Their clans can number upwards of a hundred individuals in the most prey-dense territories, though most are smaller.
The highland hyena is unique to the northwest of the region. As the name suggests, they have specialized into surviving in higher altitude climes, but can also be found in the remaining pockets of surrounding forest (and once had a much larger range across the former northern forests). Their spotting is often less visible than their lowland relatives, though their base coloration is similarly variable. Their clan sizes are substantially smaller than the scrub hyena, as they inhabit regions with much lower prey densities.
Both are closely related (whether they are subspecies or separate species would be subject of debate by taxonomists) and can produce viable young. Heavily hybridized populations are common where their ranges overlap. Scrub hyenas appear to breed more readily with dispersing male highland hyenas than the reverse.
Hyenas occupy an overall minor space in most of the Wardi cultural sphere. They are noted negatively as man/corpse eaters, but are generally regarded as intelligent and powerful predators and avoid the stigma attached to man-eating scavengers. In most cases they are not ascribed much significance in comparison to the venerated lion or the massive and intimidating king-hyena, mostly being relegated to a threat to livestock and potential danger to lone travelers.
Many urban areas in the province of Godsmouth (including the outer unwalled portions of the eponymous city) have unique practices of not only tolerating but actively inviting scrub hyenas into urban spaces. These urban hyena populations have been genetically semi-isolated from their wilder counterparts for several centuries. Rather than hunting large prey, they fill similar roles to feral dogs in the urban landscape as cleaners of refuse and killers of pests, and benefit from their species being culturally regarded as powerful predators rather than lowly scavengers. They notably predate on the considerably more reviled feral dogs, and keep their populations much lower than other parts of the region. Their role is regarded as both a physically and spiritually cleansing force, with their presence neutralizing polluting elements (while not being sacred in of itself).
The Godsmouth hyenas show little fear of humans compared to their wild relatives, though their activity peaks at nighttime hours to avoid close contact. They are sometimes raised from cubs to be fully tamed (though are not truly domesticated) and used as guards or to assist in hunting (Godsmouth's designated dog hunters notably have traditions of keeping hyenas). This practice is essentially exclusive to the province of Godsmouth- hyenas rarely establish semi-urban populations in other parts of the region, and those who do have considerably greater fear of humans, usually sneaking in under the cover of night to feed on scraps and fleeing from encounters.
The status of hyenas varies in the other groups native to the region. For example:
Hyenas have a generally favorable status to the Cholemdinae, who have traditionally reckoned them as highest among predators, noting their stamina and intelligence. Body parts of hyenas are ascribed the ability to increase the wearer's stamina, and amulets carved from hyena bones are often worn while persistence hunting. Children born while hyenas are heard crying are considered to be strong and very likely to survive infancy (and will often be given names referencing the animals). The apparent androgyny of hyenas is allegorically attributed to the creation story- the first beings were dual-sexed, and split into male and female halves as part of their punishment for the theft of fire from the sun. The hyena escaped this punishment by digging into the underworld to hide and getting only its once long, luxurious tail chopped off (which was sticking out from the hole).
((TANGENT: The South Wardi have more recent common cultural ancestry to the Cholemdinae than to most of the other groups assimilated into the collective Wardi nationality. The notion of hyenas once having long, flowing tails that got chopped off in some mishap still appears in South Wardi animal folktales))
They have a largely disfavorable reputation to the Hill Tribes, and are generally regarded as gluttonous and brutish in nature. The Highlands have a naturally lower density of wild ungulates, made far lower by most grazing pasture being occupied by livestock. This causes hyenas (and other large predators) to more frequently predate on domestic animals, and thus places them directly in conflict with herders (and also makes them common rabies vectors). They are readily culled when found in proximity to villages. Hyena pelts are generally considered worthless, and culled hyenas will often be fed whole to livestock guardian dogs and their pups in hopes of teaching them to be fearless towards the predators. Were-hyenas appear in folklore- among the southwestern Hill Tribes they are most commonly the accursed spirits of cannibals, while in the northeast they are malicious witches who learned secret arts of transformation and take on these forms to wreak havoc upon their enemies.

Let’s head to the Museum’s Hall of North American Mammals to take a peek at today’s Exhibit of the Day: the Spotted Skunk and Ringtail Diorama. This scene takes place in Shiprock, New Mexico, and features a spotted skunk doing a handstand. What for? It’s a warning to discourage the two curious ringtails from getting any closer. If this pose doesn’t work, the skunk will release jets of foul-smelling musk from glands under its tail. But ringtails also combine chemistry with defensive body language. Here, one ringtail has made its tail fur stand upright, creating the illusion of larger size. If the standoff escalates, the ringtail might curve its tail over its head, and—as a last resort—emit its own smelly secretion.

I think the reason people believe chuuya would be the more open and affectionate in soukoku (as like. A romantic relationship) is because they believe him to be the mentally stable one and i think the reason people seem to believe he’s one of the few “mentally stable” characters in bsd is because he does not let himself be seen as vulnerable, and the few times we do see him go through something genuinely horrible and having a moment of vulnerability he does not really have the time to truly process it and ends up “moving on” pretty quickly (for example when he was at the flags’ funeral and adam interrupted him, or how when the sheep betrayed him dazai was immediately at his side trying to convince him to join the pm). And even if he does process it and thinks “man that was pretty fucked up wasnt it” it is never shown on screen so i feel like a lot of viewers end up seeing it as him not being bothered by these events and just a pretty chill dude that doesnt wallow in grief or self pity. But i think him never wallowing in grief or self pity is kind of a problem because in the end all he is doing is suppressing all that trauma and not really trying to acknowledge it, but at the same time when he does he ends up pinning the blame on himself (how the sheeps betrayal was his fault, the flags dying because of him). I feel like this impacts how affectionate he is too because he has built up so many walls that at the point when the flags make a party to celebrate the one year anniversary of him joining the pm he gets suspicious, then surprised and then flustered and tries acting like he doesnt care about it. All this is to say that i think him believing he cant show weakness and has to maintain the facade of being “the strongest” makes him seem like some regular degular guy (if he’s not fighting dragons) ends up him getting viewed as some mentally stable, communicative guy with maaaybe just a bit of anger issues when in reality he got so embarrassed by dazai’s corny speech in mersault that he shot him in the head with a gun
