Caddisfly (adult)

Hydropsychidae sp.


Newly emergent (wings are still wet). Multiple shades of tan, about 1/2 in. long w/ antennae almost that length. Didn't want to sit still.


Hydropsychidae lay eggs in non-impaired to moderately impaired fast flowing streams. Larvae are net-spinning filter feeders. Hydropyschidae are a free-living (non-case building) caddisfly, common all over New England. Pollution tolerance = 4.


Saw the pupa in the collection and was about to toss it out when it suddenly convulsed and out climbed the adult. So I let it sit on my leg for a few minutes to dry out.
