How do insects hear?

Not through ears like ours! Crickets hear through tiny openings on their front legs. Locusts, cicadas, and some kinds of moths and grasshoppers hear through little flat “ears” on their abdomens. Ants and mosquitoes hear with hairs on their antennae. Caterpillars receive sounds through hairs all over their bodies. All sound is made by vibrations in the air. Insects pick up these vibrations and hear very well—even without ears like ours!
