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.
Birch Bark Beetle
A small, dark brown bark beetle that infests birch trees in boreal and subarctic forests. Adults bore through bark to create characteristic gallery patterns. Outbreaks can kill weakened birch trees over large areas.
Did You Know?
The gallery patterns carved by this beetle's larvae under birch bark resemble ornate branching designs that are unique to the species.
