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).
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and
fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

This topic is about the Insect Order Odonata-Zygoptera
Beautiful damselflies are a priceless part of a trout stream's aesthetics, but they matter little to our flyboxes. The adults are too good at flying to end up in the water where the trout can reach them very often, but their nymphs are welcome prey at times.Damselflies and dragonflies are in the same order, Odonata, but they are taxonomically separated on an obscure level not built into this site, the suborder. Damselflies are in the suborder Zygoptera, the scientific name by which they're most known. None of that will help you catch trout, but it explains what the hyphen in this page's title is all about.
Biologically, damselflies are similar to dragonflies (Odonata-Anisoptera) in most of the ways that matter to the angler.

I didn't notice this Calopteryx adult before...it's beautiful.
