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.
Fir Longhorn
A small brown spondylidine beetle that specializes on fir trees across European mountain ranges. It is similar to T. castaneum but is restricted to Abies. Larvae develop under bark of weakened or dead silver fir.
Did You Know?
This species is considered an indicator of healthy montane fir forest ecosystems.
