Mantises are my very favorite insects. I had no idea they were so vicious until I saw one ripping apart a Brown Recluse Spider. The Widow really creeped me out. There's something so classically sinister about her shape. Anyway, these are all excellent, and, as usual, I have some questions! 1) How long do tarantulas usually live? 2) I've never seen a Death's Head Cockroach. Where are they found in the wild?
