I made a cartoon about jumping spiders, enjoy! 🕷️ #Arachtober #invert

Four-panel cartoon depicting a jumping spider sitting on a table. Spider says, "Don't call me cute!" A person with short hair and glasses says, "But you are! you're adorable!" Spider says: "No! I'm a deadly predator!" Person says, "You're a cuddly teddy bear!" Spider says, "I have eight eyes and fangs, I'm hideous!" Person says to a group of people, "Hey everyone, look at the cute jumping spider!" Spider says, "I'll never live this down!"

A weevil with a pseudoscorpion attached to its front leg, hitching a ride. Pseudoscorpions will often use other insects as Ubers to carry them around the forest, a commensal relationship called phoresis. It was exciting to see this in action. #invert El Septimo Paraiso Lodge, Ecuador

A Peacock Fly (Callopistromyia sp.) showing off the beautiful display on those wings! They strut around waving their wings and doing a little wiggle, an amazing behavior right in your own backyard. #Invert #Diptera #bugsky 🌿 #entomology

Macrophotograph of a Peacock Fly (Callopistromyia sp) resting on a slightly weathered metal beam. The fly holds its patterned wings upright in an elaborate, fan-like display, appearing almost butterfly-like. Each wing is intricately marked with shades of dark brown, black, white, and subtle hints of iridescent blue, creating a mosaic-like camouflage pattern. The fly’s body is robust and heavily speckled in shades of brown, black, and cream. Bright, vivid orange-red eyes stand out distinctly on its head, along with delicate antennae and fine bristles visible along its legs and thorax. The textured metal beam beneath it has faint scratches and rust streaks, providing contrast that highlights the detail and coloration of the insect.

my husband's hand for scale next to this MASSIVE cecropia caterpillar we saw in the laurentians in 2024 💪#InternationalCaterpillarDay #invert

a giant freaking cecropia caterpillar next to a big man's hand for scale. it's HUGE. like 5+ inches like 13+ centimetres. it's bright green with four reddish knobs with little black dots on them near its head and 16 yellow doodly knobs going down its back in two rows. it also has a bunch of little green knobs in two more rows along the sides. it's basically a legendary pokemon. this thing reaches its final form at level 56 or something. late-game-ass motherfucker
