Diving Beetle
A large, streamlined aquatic beetle with an olive-green body bordered in yellow. It carries an air bubble under its elytra and is a voracious underwater predator.
Did You Know?
Great diving beetles can stay submerged for extended periods by trapping a silvery air bubble under their wing covers that functions like a gill.
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.
