Individual species emerge en masse at different times, and are used one after the other, often for only a few days each year, as models for artificial fishing flies for fly fishing in trout streams. To do this, the small, slow-moving creatures excrete silk from salivary glands near their mouths which they use like mortar to stick together almost every available material into a cozy tube. However, previous studies have compared the survival of caddisflies with different cases, thereby precluding an analysis of the survival benefits of “weaker” case materials. As larvae, many eat various types of detritus, including bits of leaves, algae, and miscellaneous organic matter. As adults, many species do not eat at all during their brief time out of water. Their larvae are aquatic and build portable, protective cases out of local materials, including grains of sand, bits of leaves and twigs, and other debris. Some species don’t make cases at all.

Caddisfly larvae live in water, both running and still; in fact, according to Elsie Klots in The New Fieldbook of Freshwater Life, they are one of four orders of insects that “have become almost wholly aquatic during their immature life” (a European species lives in wet moss).Many of the pond dwellers cut and assemble small vegetation-bits into portable homes. The forewings are hairy (instead of scaly like a moth’s). When that stage is nearly complete, usually in fall, they cut open the case, swim to the surface, undergo the final molt, and begin flying.
