Juvenile Katydid On A Milkweed Leaf 2 - Tettigoniidae Stock Photography

The family name Tettigoniidae is derived from the genus Tettigonia, of which the great green bush cricket is the type species it was first described by Carl Linnaeus in 1758. In Latin tettigonia means a kind of small cicada. Many species are nocturnal in habit, having strident mating calls and may exhibit mimicry or camouflage, commonly with shapes and colours similar to leaves. The common name katydid is also onomatopoeic and comes from the particularly loud, three-pulsed song, often rendered "ka-ty-did", of the nominate subspecies of the North American Pterophylla camellifolia, belonging to the subfamily Pseudophyllinae, which are known as "true katydids"
