sorry for going to your retrospring, im on private so i cant reply to your tweet directly. the praying mantis on the graffart is actually mahiru's (ie. different pieces of the graffart merchandise include the mantis next to her). when mating, female praying mantises will cannibalize their partners (in actual nature, not all the time, thats just what theyre known for) so i think thats why. they're also able to eat (smaller) birds if they're hungry enough.
