louse fly

louse fly

▪ insect
 any insect of the parasitic family Hippoboscidae (order Diptera) characterized by piercing mouthparts used to suck blood from warm-blooded animals. Genera occur in both winged and wingless forms. The winged louse flies, parasitic on birds, are usually dark brown in colour, flat in shape, and leathery in appearance.

 The most common wingless species, the sheep ked (Melophagus ovinus), is about 6 millimetres (0.2 inch) long, red-brown in colour, and parasitic on sheep. Each female produces from 10 to 20 larvae at the rate of about one per week. The sheep ked cannot survive if separated from its host for more than several days. The parasite is of considerable economic importance because it stains wool, reducing its market value. Some insecticides are useful in control.

      The louse flies Lipoptena depressa and Neolipoptena ferrisi are found on deer. They sometimes attach to each other in chains; the first sucks blood from the host, the second from the first, and so on.
