Polycentropodidae
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 larvae of this family construct complex silken tubes in which to live. These are short and flattened, and built in hollows in rocks or other submerged objects. They are surrounded by silken threads stretched across nearby surfaces. The larvae are carnivorous, remaining in the retreat until alerted by a small animal encountering a thread, and then rushing out to attack the prey. Members of the genus '' Polycentropus'' make slender, tubular structures among the tangled stems of aquatic plants, being alerted to the presence of prey that encounters the associated silken threads among the plants. Genera These 33 genera belong to the family Polycentropodidae: * '' Adectophylax'' Neboiss, 1982 * '' Antillopsyche'' Banks, 1941 * '' Archaeoneureclipsis ...

Trichoptera
The caddisflies, or order Trichoptera, are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while Annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety of habitats such as streams, river ...
