Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.
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 support the project for an enhanced experience here.

This specimen seems to be of the same species as a dun I photographed which emerged from another nymph in the same sample.

Maccaffertium is a Latinized version of the name of the world-renowned mayfly systematist, W. Patrick McCafferty. And, mediopunctatum is constructed from roots of medi- meaning middle, and punct- meaning point, so I assume this species has some distinctive feature midpoint in its anatomy. Assuming my logic is valid, perhaps someone else can tell you what the feature is.

The distribution of this species is confined to the states and provinces lying east of the N. American continental divide.

OK....... I understood the Maccaffertium, but didn't get the 'mediopunctatum' ending. I had two years of German, but no Latin.
This one has a mark down the center of its back( dorsal), maybe that has some relevenance. I don't recall that particular marking on my specimens, but they have those distinctive markings on the belly(ventral side). I find those markings very interesting.

Flyfishing is a state of mind! .............. Q.g.
