help Eyed Click Beetle FAQ
What is an Eyed Click Beetle?
The Eyed Click Beetle (Alaus oculatus) is a large insect found across North America. It is most famous for the two prominent false eyespots on its pronotum, which evolved to intimidate and deter predators.
Are Eyed Click Beetles dangerous to humans?

Why are they called "click" beetles?
They possess a unique spine mechanism on their underside that allows them to violently snap their bodies into the air. This "clicking" action is used to right themselves if they are flipped onto their backs, and it helps them escape from predators.
