Whirligig Beetle
A small, oval, shiny black beetle that spins in rapid circles on the water surface. Its eyes are divided in two, allowing it to see above and below water simultaneously.
Did You Know?
Whirligig beetles have uniquely split compound eyes, with one pair looking above the waterline and another pair looking below it at the same time.
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.
