They play the same part in the economy of nature as the sand wasps (p. 129), but always lay their eggs externally on the skin of the host; the mag- gots consequently never prey on ^Vcra*na7«™)' those insect larvse which live in the tissues of plants or in the soil. The Flesh Flies (Sarcophaga) have a longish abdomen, with large bristles on the hinder margins of the segments. Thorax with three longitudinal streaks. The flies suck up sweat, but do not bite. The eggs develop within the abdomen of the mother; the flies lay the young larvse in dead flesh; also, if not kept clean, in wounds of human beings and animals,—sometimes, too, in the genital opening of horses, cattle, and swine, in which case the maggots live as true parasites in the vagina and uterus, causing a secretion of mucus, upon which they live. Two to three generations yearly; flfty to eighty maggots each time. Remedies: On keeping the flies from cattle, cf. p. 165; to keep them from meat, fly- nets, a gauze cover.
