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

Specimens of the Mayfly Genus Siphloplecton
1 Male Dun
This one hatched on the same April Saturday that I saw the first Hendricksons of the season.
1 Male Spinner
I went to great comical lengths to swipe this spinner from the air with a little aquarium net I carry with me while I'm fishing. Siphloplecton basale spinners fly fast and high over the riffles, and there are never very many of them, so they're difficult to catch.
8 Nymphs
This one's stunned or freshly dead in the pictures, because the water in my photographing tank was a bit too warm for him after being under the bright light for a while.
This nymph has double front tarsal claws and double gills on the first three abdominal segments.
