The maggots come out of etrate exposed skin and wander aimlessly, the soil at night to feed on the blood of the inhabitants of the hut who sleep on the foor. The larvae lacerate the victim and suck blood but do not penetrate tissues, returning to the soil after taking their blood meal. Two species of Cochliomyia, the New World screwworm, occasionally cause myia- sis in humans in North and South America, although these fies are primarily parasites of animals. Adult females lay their eggs around the edges of wounds, and the larvae invade the wounds and macerate the trauma- tized tissues. Crab lice have somewhat reduced front legs, with the second and third leg pairs stout and strongly clawed. Historical Information The association between humans and lice is an ancient one and probably represents an evolutionary relationship begun by lice and ancestral hominids. Surgical removal of the larvae from the and artists as well as by early writers on sci- ends of their burrows is recommended.
