Only two species of economically important fruit flies occur in Australia. One of these is the Mediterranean fruit fly (Ceratitis capitata) which permanently inhabits the growing areas of Western Australia.

The other is the QUEENSLAND FRUIT FLY (Bactrocera tryoni) which permanently inhabits parts of the Northern Territory, Queensland, New South Wales and the eastern corner of Victoria.

The adult Queensland Fruit Fly is approximately 6-7 mm long, and is wasp-like in appearance It has a wing expanse of 10 to 12 mm, and has mostly transparent wings marked with brown. The fly is brown marked with yellow. On the thorax a broad creamy, often pale, dorsal band runs down the scutellum, and there is a well-defined narrow pale yellow stripe on each side. The humeri, or shoulders, are pale yellow, also. The abdomen is constricted at the base, flared in the middle, and broadly rounded at the tip.
