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.

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.

despite what popular opinion may lead you to believe, some rocks actually do have scientifically-proven auras! Unfortunately, those rocks are uranium and the aura is cancer.
on a scale from Essek Thelyss to Ira Wendagoth, how dedicated are you to holding onto the slight of Ludinus Da'leth fucking over your research aims
The chili plant made a deal with their God to only be consumed by things that could spread its seeds and fly. The chili received capsaicin, making itself painful to eat for mammals, but not birds, and all was well for the chili.
Then the human shows up, tastes it, and likes the pain. So now there's this flightless fucking mammal eating the chili. Like not even a fruit bat or anything, a flightless fucking mammal chomping on the chili.
What the fucking shit, God, cried the chili, I specifically requested the opposite of this.
Now hold on, wait a moment, replied the God who talks to plants but has no idea what the fuck these apes are going to do next. It might be something cool.
And in a flash of a second, in barely fraction of the time that chili took to develop capsaicin, the humans went from walking across land bridges and rowing little boats across small waters, into building ships that could cross oceans. More humans tasted the chili, and liked the pain. They took the seeds with them, and planted it elsewhere.
See? They spread the seeds.
They're still not flying, said the chili, still feeling insulted and betrayed.
But before the conversation was over, the humans were still not done fucking around and nowhere close to finding out. The ships became machines, and another machine was invented, capable of flight. Now, not only were the humans farming chili on continents far too far away for any of the birds that originally ate it could dream of flying, but the chili flew with them to lands where it could possibly not grow, so that humans over there could also eat it and enjoy the pain.
You see? They spread your seeds and fly.
It doesn't count as keeping a promise if you only manage it by a fucking accident, said the chili, still somewhat insulted. But nonetheless, the chili thrived.
I think one of the greatest appeals of Dishonored 2 is how tactile this whole game is.
everything makes these perfect little noises, from the menu screen to typewriters to walking sounds. everything is so alive. the slight camera wobble as you walk. if you play with a controller, the perfectly put vibrations here and there.
it invites to explore, if only just for that.
jumped in excitement without thinking when mythbusters made the tennis volley on the airplane, hit my hand pretty hard on my ceiling fan
good thing i also just watched the “fans can decapitate you” myth get busted 😬
I hate when people ask me about my preference but I don’t understand their preference level. Like yes I kinda want Chinese food 10% more than I want a sandwich but if you want a sandwich like 40% more than Chinese food then I would say it’s totally reasonable we get sandwiches.
Your body must be rested and fed if you wish to be a pervert.
loving the ac twists recently usually i’m watching shows all “yes we knew that it’s a zombie you aim for the head get with the program already!”
but in ac, characters are like “ah yes we’ve obviously entered the afterlife this makes perfect sense carry on” and i’m behind the screen losing my mind “but what does this MEAN?!?”
giving birth sucks tbh. not only do you and the baby you’re birthing almost die, usually you shit yourself and often you tear your taint. then you have to push an organ out of your body (placenta) and if even a little of that remains in your body, you can hemorrhage to death or develop an infection that essentially rots your body from the inside out. even if you had a relatively “easy birth”, you bleed for weeks on end. even after that stops, your body and brain is changed for the rest of your life, the pregnancy leeched minerals from your bones, that can cause osteoporosis later. minor urinary incontinence is not uncommon, brain scans of people who gave birth show permanent changes in their brain, you’re never quite the same.
I say all of this not to say giving birth is disgusting but it is a harrowing and visceral experience. society downplays how fucking awful it is and makes it out to be a ~magical~ experience but it isn’t a magical transformative experience for everyone. it can be an extremely traumatic experience for someone who wanted to carry a pregnancy to term, much more so for someone who did not want to be pregnant in the first place or someone who knows their baby won’t survive the birth. anyway, abortion is a right. pregnancy and birth aren’t just inconvenient, it’s fucking awful.
