"Many species of polychaetes undergo epitoky whereby sexually immature worms transform into pelagic morphs capable of sexual reproduction. After fertilization, they release their gametes through rapid disintegration."
worms are out here having insane sex we can't even comprehend
Can anyone find me that one vintage-looking art piece of a beetle painting in a field? Not a painting of a beetle but the beetle itself is painting on a canvas and easel. I’ve been looking for days!
Is it this one? I couldn’t find any more information about it, apologies! It’s very cute though.
Omg you found it! Thank you so much!! 🪲💕💕
It turns out it is one of a whole series/theme of Whitsun/Pentecost postcards featuring Cockchafers, enjoy!
OH my gosh thank you!!! 🪲♥️♥️♥️

MANTISES ARE RELATED TO ROACHES??
crevicedwelling answered:
yes! while they do have differing ecologies—mantises generally are elongate, diurnal predators and cockroaches generally are flattened, nocturnal detritivores—it’s not so surprising if you take a closer look:
they are one another’s closest relatives, being grouped together in the superorder Dictyoptera, which is revealed by their many shared anatomical features.
if you compare the wing structure on these two, you’ll find the veins are very similar. to get a mantis out of a roach, evolutionarily speaking, all you’ve got to do is elongate the pronotum (roach head shield, mantis ‘torso’), elongate the legs, and enlarge the eyes.
mantises and roaches also both produce “oothecae,” tough eggcases in which eggs are protected from the environment. mantis ooths are often made of sturdy, hard foam, while roach ooths are leathery and purse-like.
the raptorial legs of mantises aren’t too greatly modified from a roach forelimb, either. roaches already have spiny legs for digging and defense; with additional spines organized in rows, there’s a powerful grasping foreleg.
additionally, some of the most basal (least changed from the original ancestor) mantises retain a number of very roach-like features, such as flat bodies, a short pronotum, and long cerci (“butt antennae”). Chaeteessa doesn’t even have the long spike at the end of the tibia segment! although I’m not entirely sure if all of these roachy structures are necessary primitive and not secondarily derived, these two do give a good look at how mantises might’ve looked before they evolved the characteristic spindly green forms you recognize today.
I want to make people see how much has been taken away from them.
Did you know that there are dozens of species of fireflies, and some of them light up with a blue glow? Did you know about the moths? There are thousands of them, bright pink and raspberry orange and checkerboard and emerald. They are called things like Black-Etched Prominent, Purple Fairy, Pink-Legged Tiger, Small Mossy Glyph and Black-Bordered Lemon.
Did you know that there are moths that feed on lichens? Did you know about the blue and green bees? The rainbow-colored dogbane beetles? Your streams are supposed to teem with newts, salamanders, crawdads, frogs, and fishes. I want to take you by the hand and show you an animal you've never seen before, and say, "This exists! It's real! It's alive!"
There are secret wildflowers that no website will show you and that no list entitled "native species to attract butterflies!" will name. Every day I'm at work I see a new plant I didn't know existed.
The purple coneflowers and prairie blazing star are a tidepool, a puddle, and there is an ocean out there. There are wildflowers that only grow in a few specific counties in a single state in the United States, there are plants that are evolved specifically to live underneath the drip line of a dolomite cliff or on the border of a glade of exposed limestone bedrock. Did you know that different species of moss grow on the sides of a boulder vs. on top of it?
There are obscure trees you might have never seen—Sourwood, Yellowwood, Overcup Oak, Ninebark, Mountain Stewartia, Striped Maple, American Hophornbeam, Rusty Blackhaw, Kentucky Coffeetree. There are edible fruits you've never even heard of.
And it is so scary and sad that so many people live and work in environments where most of these wondrous living things have been locally extirpated.
There are vast tracts of suburb and town and city and barren pasture where a person could plausibly never learn of the existence of the vast majority of their native plants and animals, where a person might never imagine just how many there are, because they've only ever been exposed to the tiny handful of living things that can survive in a suburb and they have no reason to extrapolate that there are ten thousand more that no one is talking about.
It's like being a fish that has lived its whole life in a bucket, with no way of imagining the ocean. The insects in your field guide are a fraction of those that exist, of all the native plants to your area only a handful can be bought in a nursery.
Welcome to the Earth! It's beautiful! It's full of life! More things are real and beautiful and alive than a single person could imagine!!!
