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).

Headed to northern Spain next month and plan to get on some local streams like the Ebro. Any guide referrals or information on permits etc would be greatly appreciated.
