Trichoptera, or caddis fly as they are more commonly known, can be divided into two groups, those which live in standing water (such as pond and lakes) and those which live in flowing water (rivers and streams). The species which live in standing water have cases which they make out of materials around them and feed on algae and fungus which live on the detritous (decaying leaves mostly) on the substratum. Those which live in flowing water are caseless species who live near the substrtum and build webs under water much as spiders do.

Caddis flies spend most of their lives as larvae living on the substratum of water bodies before they pupate and enter their imargo (adult) form.
The caddisflies, or Trichoptera, are represented in the Southeast by 544 species, belonging to 78 genera in 22 families, constituting 40 percent of the continental caddisfly fauna.
Caddisflies feed by shredding dead leaves, collecting detritus and algae and microcrustaceans from the bottom, filtering food items from the water column, scraping algae from stable solid substrates, piercing individual cells of filamentous algae, and preying on other insects.
Among all 1,653 caddisfly species known in North America (including Greenland and Mexico; Morse, 1993), 104 (six percent) are endemic to the Eastern Highlands, defined as the Cumberland Plateau, Appalachian plateaus, Appalachian Mountains, and Piedmont (Hamilton and Morse, 1990), and 63 species (four percent) are endemic to the southern Appalachian Mountains.
