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 Polycentropodidae are a family of trumpet-net and tube-making caddisflies. There are at least 30 genera and 720 described species in Polycentropodidae. The type genus for Polycentropodidae is Polycentropus J. Curtis, 1835.
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.
