The Hydropsychidae are a family -level taxon consisting of net-spinning caddisflies. Hydropsychids are common among much of the world's streams, and a few species occupy the shorelines of freshwater lakes. [1]

The Hydropsychidae family, commonly referred to as net-spinning caddisflies, includes a variety of freshwater insects known for constructing silk webs in streams and rivers.

Ecology Distributed throughout North America, there are 146 species in 10 genera. Larvae and adults range in length from 6-9 mm and can be found in rivers and streams with moderate to high current velocities. Feeding mainly on aquatic invertebrates, Hydropsychidae use silk nets to catch their prey. QuickTime Movies Additional Links Bibliography

2020年6月11日 · Net-spinning caddisfly larvae (Family Hydropsychidae) are busy using homespun nets to capture small particles like leaf detritus and even animal parts from the water column. Similar to spiders, this crafty critter spins its special net out of silk.

In Hydropsychidae the ventral surface of the head has an area of fine transverse ridges that are used in stridulation (Figure 38.7 (g)– (h)). The larval eyes, composed of several individual stemmata, occur laterally on the head capsule (i.e., the parietal sclerites).

Net-spinning caddisflies (Trichoptera: Hydropsychidae) are among the most well-known aquatic insects. Larval hydropsychids filter food particles from flowing water using silken mesh nets rigged to retreats made of silk and bits of mineral and plant material. These little “fishing shacks” are common features of stream bottoms worldwide.

Information on the biology of Hydropsychidae can be found on page 128. Hydropsychidae do not make cases. All three of their thoracic segments have sclerotized dorsal plates. Hydropsychidae have branched gills on the ventral side of their abdomen and a …

The family Hydropsychidae is nearly ubiquitous in streams and rivers, with over 1600 described species worldwide. Hydropsychidae is ecologically important and its larvae play key roles as indicators of water quality.
