High quality collection of katydid sounds ringtone

Katydids are usually green and camouflaged to blend in with foliage, more commonly heard than seen. They have a body taller than it is wide and thin and hind legs that are longer than the other pairs of legs. Some characteristics that distinguish katydids from other orthopterans include having the wings held vertically over body (like a roof of a house), hearing organs on the front tibia, all tarsi with 4 segments (crickets have 3), a typically flattened and sword-like ovipositor, and very long, thin antennae as long as or longer than the body (in grasshoppers the antennae are always relatively short and thickened).
