The black-flies are the daylight pests of early summer, and ere they are gone, the horse-flies and deer-flies are at hand to remain through midsummer; also the bot-flies; which, though they do not bother us, are aggravating to live stock beyond all proportion to their number and size. All these transient pests are two-winged flies (members of the order Diptera), belonging to a very few families. In all of them, the larvae live in situations very different from those of the adults. The larvae of the blood-sucking flies—black- flies and mosquitos and horse-flies —are mostly aquatic. The young of the bot-flies are parasitic in the bodies of animals. In all of them, it is the females that pester the live stock, the blood-sucking flies by biting, and the bot-flies by the operations attendant upon laying their eggs. The mosquitos represent the best-known of these families (Culicadae). These do most to make the night interesting. They have a soft little hum that probably would be counted among the sweet sounds of nature, were it not accompanied by so strong an appetite for blood. They come earliest in the spring and stay latest in the fall. They breed in stand- ing water—especially in shallow and temporary pools. Rain- fig 1:0.
