Epeorus albertae (Pink Lady) Mayfly Nymph Epeorus albertae (Pink Lady) Mayfly Nymph

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.

Had a cloud of these flying over me for an hour or so last night while waiting for march browns. I was hoping for a female to go along with the males I was catching but it didn't work out. This guy was collected from the Au Sable system in northern MI. He is 12mm long. Two tails, hind wings are present. The only thing is I don't know if you could call the wings mottled, or does that only apply to the duns?

Whoops, tried uploading as an attachment but it isn't popping up after it uploads.

Not Siphloplecton. Heptageniid of some type. grey fox spinner? Male M. vicarium would be my guess. But it may be some other Mccaffertium species. I'll defer to the experts. Here is a recent photo of a male Siphloplecton basale spinner http://www.troutnut.com/topic/7995/Springtime-fun

Gracias, gentlemen. I actually considered vicarium and discounted it because of the color. Rookie mistake, I guess.

Mack,
Plenty more photos where that came from. All sorts of angles, etc. Just gotta edit.

Thanks again,
Alex
