Knowra Tettigoniidae Tettigoniidae Tettigoniidae is a family of orthopteran insects known as katydids or bush-crickets. Most have long antennae, and many produce sounds by rubbing their wings together.
Stridulation : Sound production by rubbing together specialized body parts. Many katydids make calls by rubbing a toothed wing vein against a scraper on the other wing.
Orthoptera : An insect order that includes grasshoppers, crickets, and katydids. Tettigoniidae is one of the major families within this order.
Bioacoustics : The study of sound production and reception by living organisms. Researchers use katydid calls to study communication, biodiversity, and acoustic adaptation.
Gryllidae : The cricket family, a group of orthopterans that includes house crickets and field crickets. Crickets are close ensiferan relatives, but their body shape and sound-producing structures differ from katydids’.
Copiphora gorgonensis : A Central American katydid species with a complex ear structure in its forelegs. Its ear has been studied as an unusually elaborate example of insect sound reception.
Tegmen : A leathery forewing that protects the hindwing and can bear sound-producing structures. Katydid song-producing files and resonating areas occur on the forewings, or tegmina.
Ensifera : An orthopteran suborder that includes crickets, mole crickets, and katydids. Katydids belong to Ensifera, whose members commonly have long antennae and sound-producing organs.
Acoustic monitoring : The use of recorded sound to detect, identify, or track organisms and environmental change. Distinctive katydid calls can reveal species presence in vegetation that is hard to survey visually.
Acrididae : The grasshopper family, a diverse group of short-horned orthopterans. Grasshoppers typically have short antennae and belong to a different orthopteran suborder.
Acanthoplus discoidalis : A large flightless katydid native to parts of southern Africa. This species illustrates the family’s diversity beyond familiar leaf-mimicking forms.
