The Limnephilidae is one of the most species-rich Trichoptera families of northern temperate regions, but only a few are known from tropical areas and the Southern Hemisphere. For this reason they are often known as northern caddisflies.

The adults are usually brown in colour, often with narrow mottled or patterned forewings and much broader, transparent hindwings. The aquatic larvae construct portable cases from a wide variety of plant and mineral materials, sometimes even snail shells. Cases of young larvae often looking completely different from those of larger instars. Larvae tend to be eruciform (with a thickset head and thorax), rather slow-moving, and usually feed by browsing algae or scavenging animal remains. They pupate within the larval case, the pupa swimming to the surface before flying away as an adult. For most species the life cycle is completed within one year.

The family includes one extraordinary aberrant genus, Enoicyla, whose larvae are terrestrial, living among moss and leaf litter. The females of Enoicyla have only vestigial wings and are flightless.
