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.

Oil Beetle

A large, flightless beetle with shortened elytra and a swollen abdomen. It secretes an oily, blistering compound called cantharidin when threatened.

Did You Know?

Females can lay over 1,000 eggs, but larvae must hitch a ride on a solitary bee to survive.
