Order Trichoptera - The Trumpetnet and Tubemaking Caddisflies
Distinguishing characteristics - The anal claw of Polycentropodidae is hook shaped (Fig. B). The trochantin is pointed (Fig. C). This pointed trochantin helps distinguish Polycentropodidae from the Family Psychomyiidae, which has a hatchet shaped trochantin. Their abdomen lacks gills (Fig. D) and the mesonotum is largely membranous (Fig. E). They do not make portable cases.

Tolerance Value - 6

Feeding Group - Filterer

Notes - Although found in many areas of the state, these caddisflies are not usually collected in large numbers. They live in a variety of aquatic habitats which usually have a slight current, and a few species can be found on lake bottoms. They are mostly collectors, and filterers, but there are some predatory species. They generally build nets that are constructed in various shapes, they don't build cases. The size of the trumpetnet and tubemaking caddisflies at maturity can go up to 25 mm.
