Female Attenella margarita (Little Western Blue-Winged Olive) Mayfly Dun Pictures

I found this dun unusually late in the year for anything in the Ephemerellidae family in the East. It's also small for that family.

This mayfly was collected from Willowemoc Creek in New York on September 4th, 2006 and added to Troutnut.com by Troutnut on October 3rd, 2006.

My Ephemerellidae keys are pretty much garbage when it comes to identifying female duns. I'm wondering if anybody has any insight on this one based on personal experience.

There can't be all that many tiny olive Ephemerellids hatching in September. My tentative guess would be Serratella.
