Wheel Bug

The largest assassin bug in North America, named for the distinctive cogwheel-shaped crest on its thorax. It delivers an extremely painful bite if handled.

💡

Did You Know?

Its bite injects cytolytic venom that dissolves tissue, producing pain reported to be worse than a wasp sting lasting for days.

Ant Damsel Bug

A slender brown predatory bug whose nymphs remarkably mimic ants for protection from predators. Adults lose the ant-like appearance and become typical damsel bugs. It is a beneficial predator in European gardens and fields.

💡

Did You Know?

The young nymphs are such convincing ant mimics that they even walk with a jerky, ant-like gait, fooling both predators and entomologists at first glance.
