For The Dragon Gifs Post You Reblogged, Could You Elaborate On Your Tags? As Someone Who Loves Speculative/fictional

“I could never be an entomologist. bugs creep me out” sucks to suck because I’m a real-life pokemon trainer. like look at these and tell me they’re not pokemon

like are you serious. have fun doing whatever you’re doing ill be at the arthropod zoo… also known as the motherfucking pokemon center

Do you like vintage scientific illustrations?

Do you like not spending huge amounts of money on them?

This website has a huge collection of high quality vintage illustrations that you can download FOR FREE

They got pretty much everything!! Vintage maps, mushrooms, flowers, trees, bugs, birds, corals, fish, palm trees, feathers, tropical fruits, you name it!!

They even got some works of my dude Ernst Haeckel on there!!!!

I could go on and on but I suggest you check it out yourself. Personally, I will be covering my entire apartment with these once copyshops are open again. But even if you don’t want to do that, just browsing all these beautiful illustrations is a great way to spend your time. 

Have fun and stay save!

my 2 moods are:

- im baby

- im small bastard man i wanna hiss at the sun

it’s crazy how much diversity there can be in one species…these are all pictures of the same bird species (red-tailed hawk)

The Grackles

are also still around, and some are still feeding babies, but molting has also begun, giving some of them the best and most dramatic looks. As if they couldn’t already do that with their plumage fully intact!

Part 2 of cino art tips is some basic tips on shape and silhouette design which are also principles I think about a lot :)

(also i'm so sorry i chose comic sans to write this in idk what i was thinking but i already flattened the layers)

i don't have any other obvious tips off the top of my head rn but feel free to ask anything you are curious about! i love getting asks uwu

Leafy Sea Dragon (Phycodurus Eques)

enjoying the variation in these handsome Graphocephala versuta, including the last poor hopper who has a mite sucking on its head

the paralyzed cicadas I picked up from a failed cicada killer nest are the perfect material to show off some cool features of insect anatomy! (although the wasp’s venom would keep them alive for her larvae to eat, I froze them to make sure they’re fully dead for dissection).

cicadas are powerful, fast fliers, and all of their thorax is taken up by a bulk of reddish, stringy flight muscles, which I’ll talk more about later. this cicada is a female, so her abdomen is full of white, elongated eggs that she will insert into tree bark with the bladed ovipositor at her rear.

the male cicada’s abdomen, however, is almost entirely empty, and that air-filled space is used as a resonator for his loud calls. the biggest structure visible there is a curved pair of muscles that deforms the tymbals, producing a click with every contraction.

here's a view of the complete muscle, and the tymbals themselves which look like overlapping plates on his belly. if you're curious what the white frosted appearance is, some Neotibicen have a coat of waxy powder or pruinescence; this male N. tibicen is particularly pruinose.

onto the flight muscles:

powered flight is a pretty complex mechanism in any organism, and is never so simple as just flapping wings up and down, but most insects power their flight in a really unintuitive way (at least for us vertebrates): they contract muscles in their thorax that aren’t even attached to the wings!

this method of flight is called indirect flight, in contrast to the direct flight of the dragonflies and mayflies where each of four wings is directly attached to a muscle and can flap on its own.

instead, most insects have a longitudinal (image 1 above, d below) pair and a vertical (2, c) pair of muscles that deform the shape of abdomen, pulling the upper segment of the thorax (notum) up and down, and this moves the wings which are attached to the notum. useful indirect flight gif from wikipedia found here

even if compressed manually, the dead cicadas "flap" their wings due to the motion of the notum:

insect flight is a lot more complicated than this simplified look at them, but I think these cicadas offer a pretty good look at how most insects get around essentially by squishing themselves internally!
