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.

Mother-of-Pearl Caddis

A large European caddisfly with translucent wings that shimmer with iridescence. Larvae construct flat cases from pieces of dead leaves.

💡

Did You Know?
