Six legs, mostly
Among the animals, this category covers beetles, bugs, bees and their kin. Spiders turn up too, as they do in everyday speech, though strictly they are not insects; if you want them specifically, the spider category is more focused.
Diagram, ornament or mood
The labelled cutaway belongs in a biology lesson or an entomology handout, where the numbered parts do the teaching. The steampunk beetle is decoration — jewellery listings, game assets, posters. The spider on a key is about atmosphere, suited to mysteries and escape rooms.
Legs and antennae
These are the parts that break first. A good file shows every leg and both antennae intact, with thin segments that do not dissolve into the background when you shrink the image.
