Jet Beetle

A tiny, goggle-eyed rove beetle that hunts with a remarkable extendable labium tipped with adhesive pads. It can also skim across water surfaces using a unique chemical propulsion mechanism.

💡

Did You Know?

Stenus beetles secrete stenusine from pygidial glands, which lowers water surface tension behind them, propelling them across water at speeds up to 70 cm per second.

Paddle-tailed Darner

A large, boldly marked darner of western North America with distinctive paddle-shaped cerci. Males have bright blue and green abdominal spots.

💡
