The bluebird's preferred insect prey include grasshoppers, crickets, katydids, and beetles. They also consume moths, termites, cockroaches, katydids, crickets, flies and lacewings. Caterpillars, moths, katydids, cicadas, small lizards, and other prey are fed to the young. Crickets, like other Orthoptera (grasshoppers and katydids), are capable of producing high-pitched sound by stridulation. Crickets and katydids ("mushi") were the staple symbols of autumn in haiku poetry. Orthopteran insects, including crickets and katydids (family Tettigoniidae), have been especially well-studied for sound production. Many katydids exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves. Phaneroptera is an Old World genus of katydids in the subfamily Phaneropterinae. They are also known as false katydids or round-headed katydids. Alison Brie executive produces alongside The Katydids, Matt Miller, and Cap Gun TV. For example, the Amazon basin rain forest is home to over 2000 species of katydids.
