Ephemerella excrucians (Pale Morning Dun) Mayfly Nymph Pictures

I spent a while with a microscope to fairly positively identify this specimen as Ephemerella excrucians.

This mayfly was collected from the Bois Brule River in Wisconsin on June 9th, 2005 and added to Troutnut.com by Troutnut on May 26th, 2006.
