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'm a salmonid research scientist with the Washington Department of Fish and Wildlife since 2022. I completed my Ph.D. in 2014 at the University of Alaska. I created Troutnut.com in February 2004 and worked on it full-time during various short breaks from school and work.
