grasshopper-cricket
Pseudoscorpion

Pseudoscorpion

A tiny, tail-less relative of true scorpions, complete with a pair of oversized pincers on a body barely bigger than a grain of rice. Often overlooked entirely, it spends its life hunting even smaller arthropods in leaf litter, bark, and sometimes old books.

Jumping Spider

Jumping Spider

A compact, often furry, day-active spider with unusually large forward-facing eyes that give it an alert, curious look, known for stalking prey and pouncing in a sudden leap.

A small, deep orange sulphur butterfly with dark wing borders and a low, wandering flight, named for a faint dark mark that suggests a half-closed, sleepy eye.

butterfly
Flea

A tiny, wingless, laterally flattened insect built for moving swiftly through fur, famous for its powerful hind legs that allow it to leap many times its own body length.
