Pteronarcys californica

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

Dorsal view of a Epeorus albertae (Heptageniidae) (Pink Lady) Mayfly Nymph from the East Fork Issaquah Creek in Washington
This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.
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.

Caddisfly Species Brachycentrus appalachia (Apple Caddisflies)

This is a "wind-shield wiper" hatch -- it slows traffic on the freeway which winds through the valleys of several famous trout streams in the Catskills, which have thick hatches of the Apple Caddis in the Spring.

The common name comes from the bright apple-green color of its abdomen.

Where & when

Time of year : May

This species produces intense, reliable hatches in the Catskills sometime in between the peaks of Ephemerella subvaria (Hendricksons) and Ephemerella invaria (Sulphurs).

Special thanks to Lloyd Gonzales, author of the excellent book Fly-Fishing Pressured Water, for helping to sort out the Brachycentrus species and common names.

In 2 records from GBIF, adults of this species have been collected during May (50%) and April (50%).

In 1 record from GBIF, this species has been collected at elevation of 1614 ft.
