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.

Thanks for the pics of this genus Jason. I had sampled a creek that I live close to and had collected something that I thought was Siphloplecton, but afer seeing your photos it must be Ameletus.

Looks similar to me. It's amazing how the colorations can vary.

Nice pic Caleb. That's gotta be the same mayfly.

The real distinguishing characteristic is in the mouth parts, which can be verified on my specimen, but the markings are so similar that we've clearly got the same insect.

The thing that threw me was the three dark lines on the underside of the abdomen.
