Bean Weevil
A small, mottled grayish-brown beetle with a compact, somewhat wedge-shaped body. It is a major stored-product pest that develops inside dried beans and other legume seeds.
Did You Know?
Multiple larvae can develop inside a single bean, and adults can fly directly to bean fields to infest crops before harvest.
Trap-Jaw Ant
Has the fastest-closing jaws in the animal kingdom — mandibles snap shut at 64 m/s (230 km/h) with force 300 times the ants body weight, allowing it to catapult itself to safety.
Did You Know?
Trap-jaw ants can launch themselves into the air by snapping their mandibles against the ground — they use this as an emergency escape mechanism against predators.
