There are more species of caddisflies (Trichoptera) than of all other primarily aquatic orders of insects combined. Ecosystem services provided by Trichoptera are also unusually diverse. They capture and assimilate many forms of nutrients and transform them for use by other freshwater and riparian organisms; they also stabilize stream gravel habitat. Humans employ them to monitor water quality; their labial silk, produced under water, may serve as a model for various new textiles. An increasingly credible phylogeny of families provides a foundation for interpreting and hypothesizing the many functional traits of caddisflies and their corresponding ecological services. The use of angiosperm plant tissues as food and case construction material by the earliest ancestors of infraorder Plenitentoria—by at least 175 Ma—may provide insight into the timing of the origin of angiosperms.
