Order Diptera


Flies differ from other insects by having only two true wings. The hind pair is reduced to small, club-like organs called halteres. A few flies, such as the sheep ked, are wingless. Many flies, including mosquitoes and horse flies, have piercing-sucking mouthparts. The house fly, however, possesses another type known as sponging mouthparts, which it uses to sponge up liquid food. Metamorphosis is complete, the life stages being the egg, larva, pupa, and adult. The larvae are generally called maggots, and the pupal cases are called puparia. Flies are found around flowers, decaying vegetation, on animals and in houses and barns.
