Male Ephemerella aurivillii Mayfly DunMale Ephemerella aurivillii  Mayfly Dun View 14 PicturesThis is the most widespread species of Ephemerella, and also the most abundant in some places, but nobody I've talked to seemed to know what its duns looked like, and there were no pictures of its duns online or in any angling books.
