Acrididae (locusts and relatives)

This family of short-horned grasshoppers includes more than 5,000 species. The antennae are shorter than the body. Females do not have a long ovipositor. They excavate a hole in the ground and deposit 30-100 eggs together with a fluid which hardens and forms an egg pod. Males stridulate during the day by rubbing the inner side of the hind femora (which has a row of projections) against the closed forewings, producing a buzzing sound.

The Acrididae includes the swarm forming (gregarizing) locusts. Some species found in tropical and subtropical regions are notoriously destructive.

For beneficial Acrididae see the Acrididae (weed bioagents).
