hawk moth

insect

also called sphinx moth, or hummingbird moth

any of a group of sleek-looking moths (moth) (order Lepidoptera (lepidopteran)) that are named for their hovering, swift flight patterns. These moths have stout, bullet-shaped bodies with long, narrow forewings and shorter hindwings. Wingspans range from 5 to 20 cm (2 to 8 inches). Many species pollinate (pollination) flowers such as orchids (orchid) and petunias (petunia) while sucking nectar. The proboscis (feeding organ) of some species measures up to 32.5 cm (13 inches). Some hawk moths migrate.

The common name for Acherontia atropos, death's head moth, derives from the fancied facsimile of a human skull on the upper surface of the body. Common in Europe and Africa, these moths have a short proboscis and often feed on honey from beehives. They produce loud chirping or squeaking sounds by forcing air out through the proboscis. In the larval (larva) stage they make distinct cracking noises.

The species Xanthopan morganii praedicta, named in honour of its predicted existence by Charles Darwin (Darwin, Charles) and Alfred Russel Wallace (Wallace, Alfred Russel), exclusively pollinates the Madagascar orchid, Angraecum sesquipedale. The proboscis of this hawk moth is long enough to reach the nectar receptacle of the orchid, which is between 20 and 35 cm (8 and 14 inches) in length.

The leaf-feeding larva generally has a smooth body with a characteristic dorsal caudal horn, hence the common name hornworm. Two economically destructive North American species, the tobacco, or southern, hornworm (Manduca sexta) and the tomato, or northern, hornworm (M. quinquemaculata), attack tomato, tobacco, and potato crops. These leaf-feeding pests are green and can be 10 cm (4 inches) long. Control includes the use of a natural enemy, the braconid wasp (braconid) (Apanteles congregatus), which parasitizes the larvae. Pupation (pupa) occurs in an earthen cell or loose cocoon at the soil surface.
