Female Hesperoperla pacifica (Golden Stone) Stonefly AdultFemale Hesperoperla pacifica (Golden Stone) Stonefly Adult View 13 PicturesMy blurry photo at first makes it look like there might be a distinct notch in the subgenital plate of this specimen, but that's not the case -- just a poor photo.

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!
