Giant Swamp Leaf Beetle
One of the larger species of reed beetle, with a metallic golden-green to coppery body and distinctive long antennae. Adults rest on emergent aquatic plants in wetlands.

Horned Passalus
A large, shiny black beetle with a small horn on its head, found in rotting logs. It lives in family groups where adults and larvae communicate by stridulation.
