Q:

What are some insects that jump?

A:

Insects that jump include the froghopper, the flea, the grasshopper and the katydid. Insects that jump often use their ability to escape from predators, and their jumps are sometimes proportionally equivalent to a human leaping many hundreds of feet.

The froghopper is a tiny insect just 1/5 inch long but with a powerful jumping ability that allows it to catapult more than 2 feet into the air. Strong leg muscles store the energy, then release it all in one burst, subjecting the froghopper to about 400 times the force of gravity as it accelerates to speeds of about 13 feet per second. The froghopper's jump is so fast that even with a high-speed camera capable of shooting 2,000 frames per second, the insect's jump takes up only two frames.

The flea, a bloodsucking parasite, also stores up energy for a jump, leaping from the "toes" of the legs.

Grasshoppers are some of the best-known jumpers of the insect world. The muscles they use to leap are 10 times stronger than those of humans; only clams have stronger muscles in the animal kingdom.

Katydids look like grasshoppers but are more closely related to crickets. They are notable for their camouflage that makes them look like leaves or other plants in their environment.
