Insect Pests of House and Garden. 665 VII. Flies. Flies are among the most persistent and annoying of household pests. Although they are so common and compel one's attention so often during the summer months, there are several erroneous notions and much ignorance concerning them. Many persons cannot tell how many wings a house-fly has; housewives will often say that little flies grow into big ones; it is a common notion that all flies bite; but few know the winter habits of the house-fly, and not many know the life- story and breeding habits of house-flies. The common house-fly is scientifically named Miisca domestica, but there are several other kinds of flies which are often found in houses. It is the stable- V y^ h fly which has mouth-parts adapted for piercing the skin or " biting," while the common hoMse-fiy only scrapes or tickles the skin. The duster- fly or " buckwheat-fly " is a frequent visitor in houses, and is often found congregated in large companies in attics or little-used rooms in the fall or winter. Most housewives are also familiar with the large bluebottle or blowfly, which lays its eggs on exposed meat. Most of these flies look alike to the housewife, and as they differ in size, the conclusion is reached that the little ones grow into bigger ones, but in- sects do not grow after they attain wings. The common house-fly (Fig. 29) breeds out of doors in manure and dooryard filth, apparently preferring horse manure. Its long, white eggs (6 in Fig. 29) which are laid on the manure, hatch the same day into white maggots {c in Fig. 29), which feed on the manure for about a week, and then change to a hard, brown puparium {d in Fig. 29), in- side of which they transform through the pupae stage in five or six days. Thus the whole life-cycle of the common house-fly,
