Recent observations indicate that, on two occasions at least, two species of wild flies came into houses and acted like species we regard as house flies. The two species are: Cochliomyia americana Cushing and Patton and Ceratoxys latiuscula (Loew), which will be discussed in the order above. Cochliomyia americana, the screw-worm fly, a Calliphorid, is usually a wild elusive, swift-flying, out-of-door creature, occasionally attacking man, but more frequently ovipositing in the wounds of domestic animals. In Utah the closest they were found to a dwelling was when two were captured feeding on a fresh deer head in a garbage can near a backdoor. In all my Iowa collecting, except at Adair, I have found this species out-of-doors and wild.
