Order Mallophaga


The chewing lice are wingless, flat-bodied insects, parasitic on birds and, to some extent, mammals (warm-blooded animals that have hair). They have chewing mouthparts and feed on bits of hair, feathers, scales and dried blood. They develop with gradual metamorphosis, the life stages being the egg, nymph, and adult. All adults are wingless. Chewing lice attack all kinds of wild and domesticated birds as well as many of the common mammals. The eggs are glued to the feathers or hair of the host.
