Guide To The Insects Of Connecticut Part Iv

Excerpt from Guide to the Insects of Connecticut, Vol. 6: The Diptera or True Flies of Connecticut; First Fascicle; External Morphology; Key to Families; Tanyderidae, Ptychopteridae, Trichoceridae, Anisopodidae, Tipulidae The habitats of adult flies are usually limited to areas adjacent to favorable breeding places, although under certain conditions they may fly or be blown by winds some distance away. The presence of swarms of midges, numerous mosquitoes, or an abundance of house flies, usually indicates that breeding has taken place in the Vicinity. This is particularly important in the control of species of economic significance. In any discussion of habitat, then, it is the larval habitat that is more important. The variety of places in which these insects breed and their flying ability accounts for their presence in all parts of the state. Although the requirements of fly larvae are diverse, for the majority of species a moist environment is essential. Many species are aquatic, living in ponds, pools, or streams. The volume of water necessary need not be large. The reservoirs'of pitcher plants serve as the breeding place for some. Others occur in the water in cavities in trees. The imprints of cattle hoofs in low pastures frequently serve as breeding places for mosquitoes, and temporary pools on the salt marshes are notorious in this respect. Some species, as our black-flies and net-winged midges, live only in rapidly running streams. In large ponds and lakes the species which breed in the small shallow marginal pools may differ from those found in deep water, and cer tain types of lakes may have distinctive bottom-dwelling species. Some fly larvae, as rat-tailed maggots of the genus Eristalis, prefer water containing a great amount of decomposing organic matter and live in filth.
