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.

Male Psychoglypha (Limnephilidae) (Snow Sedge) Caddisfly Adult from Spring Brook in Washington

This Psychoglypha adult was found clinging to my garage door in the evening on April 9, 2013. It measures 21 mm in length, from the front of head to the end of wings. It is my hope that Creno will be able to identify it to species based on the image of its genitalia. However, if other images are required for a species ID, the specimen is available, so they can be easily taken. Thanks, Roger Rohrbeck, Mercer Island, WA.
