Ecologically the group is very varied; many occur in decaying vegetation and dung or among fungi while some occur in mammal or avian nests; sometimes being associated with a single species. The name ‘pinacate’ is an Aztec word which literally means “black beetle.” As their name suggests, these beetles are famous for producing a stinking chemical as a defensive mechanism. CLOWN BEETLE-The saprinus pennsylvanicus has an oval or rounded, shiny metallic green colored body. The clypeus and frons are smooth; without a suture, and the clypeus is prolonged into a ‘snout’.
