Abstract :	Trichoptera, or caddisflies, are one of the larger orders of aquatic insects, with approximately 10,000 described species and an estimated total of 50,000 species worldwide. In North America, over 1,660 species are known (Morse 1993). Adult caddisflies are moth-like insects and are mostly nocturnal. The larvae of virtually all species are aquatic, living in springs, seeps, streams, rivers, lakes and ponds, including temporary as well as permanent streams and ponds. A small number of species are terrestrial or marine. Trichoptera often are abundant in aquatic habitats, and therefore play vital roles in the ecology of aquatic ecosystems (Wiggins 1996). They contribute to the transfer of energy and nutrients through trophic levels. Because the larvae of most species are entirely aquatic and susceptible to a variety of stressors, Trichoptera are considered to be excellent indicators of water quality (Mackay and Wiggins 1978).
