Male Epeorus vitreus (Sulphur) Mayfly DunMale Epeorus vitreus (Sulphur) Mayfly Dun View 4 PicturesThis is my favorite mayfly from 2004, and it appears on my popular Be the Trout: Eat Mayflies products. Check them out!

Female Epeorus (Little Maryatts) Mayfly DunFemale Epeorus (Little Maryatts) Mayfly Dun View 5 PicturesI'm guessing this female is of the same species as this male dun, because they came from the same pool at the same time and the size matches, although the males and females would look very different in this case.
