If I add more to this, I really want to make sure every bug-person added has something unique about them. I was looking into adding something cool like a tail-goo shooting attack for Firefly Men, but beyond that I have a hard time coming up with ideas; Butterfly, Damselfly, Dragonfly, Grasshopper and Beetle Men don't leave much room for interest, aside from maybe using KICK_ATTACK_HIGHVEL for grasshoppers.
War beasts might be another thing to add. A battle beetle and a war worm would be easy enough to do, and if I can figure out the interaction I'd love to have something with a fearsome roar effect.
