Male Epeorus (Little Maryatt) Mayfly Dun Pictures

This Epeorus dun managed to emerge successfully even though it had apparently long several legs at some point and only partially grown them back.

This mayfly was collected from the West Branch of the Delaware River in New York on May 15th, 2007 and added to Troutnut.com by Troutnut on May 18th, 2007.
