Female Heptageniidae (March Browns, Cahills, Quill Gordons) Mayfly DunFemale Heptageniidae (March Browns, Cahills, Quill Gordons) Mayfly Dun View 10 PicturesThis specimen is really strange, very different in form from any other mayfly I've seen. Unfortunately it was found alone crippled in an eddy and in pretty bad shape, and I couldn't find any others like it.
