Explanation of Names
Hydropsychidae Curtis 1835
~160 spp. in 11 genera in our area(1), almost 1000 spp. in ~60 genera total
adults 6-19 mm
larvae in streams and rivers, adults in nearby vegetation
larvae feed on algae, diatoms, crustaceans, and immature aquatic insects that are swept by the current into their silken nets
larvae do not build a case; they seek shelter in debris and under stones, and spin a concave silken net, facing upstream, at the entrance to their retreat, then position themselves at the downstream end of the net to await prey
