#Invertober

2025-12-09

Today for #ArtAdventCalendar, I have all of the insects I painted in 2024 for #Invertober (I missed it this year, due to moving). Rather than going with the official prompt list, I focused on invertebrates found in my home state of Colorado.

#SciArt #InvertArt #InsectArt #watercolor

Many watercolors of invertebrates, cut out and placed on a black background. Includes: Mormon cricket, tiger beetle, brown tarantula, rocky mountain capshell, cave pseudoscorpion, say's stink bug, mountain cicada, mussel, millipede, grass carrying wasp, Colorado soldier beetle, desert centipede, robberfly, yellowjacket, cow killer, rocky mountain snail, boxelder bug, silvery blue (butterfly), snakefly, tiger moth and caterpillar, two spotted stinkbug, rocky mountain billbug, thread-waisted wasp, colorado potato beetle, firefly, mountain pine beetle, ornate checkered beetle, golden blister beetle, rabbitbrush beetle, pigeon sawfly, and an extinct wasp... I think I got all of them.

My slightly late offering for day ten of #invertober (common earthworm) 🪱

Did you know earthworms have a special lip-like first head segment called a prostomium (meaning 'before the mouth')? They use it to sense and manipulate food, and move through soil!

Today is World Egg Day so here's a painting I did for #Invertober last year of a sweet mama desert centipede and her clutch of eggs.

Centipedes never actually meet to reproduce - males just drop off a spermatophore somewhere on the ground for a female to pick up and inseminate herself with later. Females do all the parenting, too, protecting, feeding, and even grooming her clutch of baby 'pedes.

For #Arachtober today I have another painting I did for #Invertober last year, of a Boulder cave pseudoscorpion - Larca boulderica. First discovered by a particularly curious family of cavers in 2008, the species was finally formally described as a unique species last year.

Painting of a round orange creature with eight legs and pokey pincers.

Today for #Arachtober I present a Colorado brown tarantula, Aphonopelma ????, that I painted for #Invertober last year. The question marks are there because there's lots of debate on whether Colorado has its own unique species (or three or more) of brown tarantulas or whether they're all just subspecies of A. hentzi, the Texas/Missouri/Oklahoma brown tarantula (depending on who you ask).

Taxonomy is hard!

#invertober Day 3 Giant green anemone (Anthopleura xanthogrammica) I tried to be interpretive with “tried” being the key word. They all can’t be winners!

Okay, I'll bite (ha!). I have a couple things to contribute to #Arachtober. Today, it's this comic I made for #Invertober a couple years ago. Pink Crab Spider party!

#spider #spiderArt

Three crab spiders are conversing in a circle. An all hot-pink one says, "I'm a Pink Crab Spider!"
The next, white with pink spots, says, "So am I!"
The third, mostly white with a yellow face, says, "Me too!"
A yellow crab spider with a green face asks, "Hey guys can I join?"
All four spiders in a row shout, "Yay! Pink Crab Spider party!"

For #invertober people, it looks like the fried egg jelly! I saw one also (in the Valencia aquarium)

Fried egg jellyfish Phacellophora camtschatica. Top of it is like a fried egg, but the orange "yolk" is quite bulbous in this individual

Initial designs for #InsertAnInvert2024, a Strawberry Squid. Not sure if I should make the photophores darker or lighter than the main body. I'll print both and see how they look.

(I do intend to add the asymmetrical eyes, just want to make sure the basic design works first.)

A fun way to discover beautiful creatures that help keep our ecosystem alive, it’s worth following @ehrenenglish.bsky.social for some fascinating updates, especially during #invertober (invertebrates are awesome all year ‘round but especially during October)
