Agricultural Experiment Station; Agriculture -- New York (State). Rural School Leaflet 1283 Story of its lije.— The small, white, slightly curved eggs are laid among decaying vegetable material, especially horse manure. They hatcli in. Eggs of a house fly. Enlarged twenty-four hours into maggots, which reach their full .growth in five or six days and change to dark brown objects known as puparia. The pupas, inside the puparia, rest quietly for about five days, and then trans- form to the adult flies. There may be eight or ten generations each season — each generation, of course, containing more flies than the pre- ceding one. Injury and control.—House flies are known to be carriers of typhoid fever, cholera, dysentery, and other intestinal diseases, and are there- fore very dangerous insects to allow in the house. All stable manure should be drawn to the fields once a week, or put in a dark, tight room or pit. The closet or outhouse should be tight so.
