The family Leptoceridae are a family of caddisflies often called "long-horned caddisflies". Leptoceridae is the second largest family of caddisflies with more than 1500 species in around 45 genera. The main identifying feature of most Leptoceridae is that their antennae are longer than those of other caddisflies. There is one genus with short antennae (Ceraclea), but it is easily identified by the pair of dark curved lines on the mesonotum.
The Hydroptilidae are a large family of caddisflies (Trichoptera) with a worldwide distribution. They are commonly known as microcaddisflies or purse-case caddisflies, in reference to two characteristic traits of this family: Hydroptilidae are much smaller than other caddisflies, rarely exceeding 5 mm (0.20 in) in length. Their larvae do not build a protective case until the final instar of their growth. At that time however, they build a typically Purse-shaped case, either portable or stuck to the substrate, in which the larva finishes growth and pupates.
The Psychomyiidae are a family of tube-making caddisflies. Members of this family are typically very similar to polycentropodids, most of them can be differentiated by the spur formula is 2-4-4, thyridial cell short, absence of the forewing fork I, and hindwing forks I and IV. Male genitalia has elongate preanal appendages, and reduced tergum IX. The larvae differ by the submental sclerites separated, foretrochantin broad, and the pupal mandible apex whip-like. Larvae construct long silken galleries.
Brachycentridae is a family of humpless casemaker caddisflies in the order Trichoptera. It is found in North America, Europe, and Asia. Georg Ulmer first described it in Germany in 1903 as a subfamily of Sericostomatidae. The type genus for Brachycentridae is Brachycentrus J. Curtis, 1834.
