This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

I went up to winterize my cabin on Sunday and of course brought along a rod and a few flies. The river was falling with suspended turbidity but I did manage a very nice end of season fish that should help to keep me looking forward, God willing, to the 2009 season. I might be done with the Delaware for 2008 but there are always Erie steelhead .
