Etymology

Origin of katydid

An Americanism dating back to 1745–55; imitative

Explanation

A katydid is a type of grasshopper with extra-long antennae. You can hear katydids on summer nights making a loud, three-note sound. Like grasshoppers and crickets, katydids make noise by rubbing body parts together — in their case, by moving a leg against a wing and producing a sound that resembles their name. Katydids have also been known as "wide-horned grasshoppers," for the antennae that are often longer than their bodies. These insects are nocturnal and use camouflage, disguising themselves as green leaves to stay safe from predators.
