Dimple-back Ground Beetle
A small, fast-running beetle with distinctive cup-shaped depressions on its elytra that create a dimpled appearance. It has iridescent bronze-green coloring and runs on wet mud.
Did You Know?
Each dimple on its elytra contains a raised center that creates a mirror-like reflection, giving the beetle a uniquely textured and sparkling appearance when viewed up close.
Eastern Toe-biter
A very large, flattened brown water bug found in eastern North America. Males carry eggs on their backs until they hatch, providing protection and aeration. It can deliver an extremely painful bite if handled.
Did You Know?
Males are dedicated fathers, carrying up to 100 eggs cemented to their backs for several weeks, regularly doing 'push-ups' at the water surface to aerate the developing embryos.
