Hydropsyche sp. from Russian River

[Mark Melton]

Found pretty much all year round except when river is in flood stage. Primarily found in moderate to fast current on gravel and cobble. Cases of larvae are of ramshackle stone with a net of silk in the front of the case. Cases of pupae are constructed of small rocks. Larvae are 15-18 mm in length. Cases of pupae are 13-16 mm and pupae are 9-13 mm.

Tied a fly a while back that looks a lot (at least to me) like the last picture.


Excellent bug photos, BTW. I am really enjoying them!
