Careful to only suggest actual insects, not arachnids (spiders of course) or myriapoda (eg centipedes which are really revolting with yellow legs). But any type of insect will do (they all have 6 legs), including coleoptera (eg beetles) and strepsiptera (the term means literally 'with twisted wings'). 
TIL that strepsiptera are the most messed-up insect i have read about since now. Because:
-Male adults live for a few hours, and never eat, their mouths now morphed to have other organs
-Female adult are neotenic (infant-like in form, ie larva-like), have no legs, wings, or even eyes, and are parasitoid to some poor other insect. That insect ends up being forced to create a vast bag-like protrusion in its abdomen, so as to prevent its own immune system from attacking the parasites or parasitoids... And the parasitoids themselves in some species get eaten alive by their own larvae!!!
So strepsiptera win. Fatality.
