Locust Borer
A striking yellow-and-black wasp mimic that attacks black locust trees in North America. Adults appear in autumn and are commonly found on goldenrod flowers. Larval boring weakens locust trunks and can cause breakage.
Did You Know?
Adults synchronize their emergence with goldenrod bloom, making autumn fields their primary mating arenas.
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.
