Pictures of 271 Mayfly Specimens in the Family Ephemerellidae:
Female Drunella grandis (Western Green Drake) Mayfly Dun
View 6 PicturesI collected this specimen while away from all my good photography equipment except the camera and one of my macro lenses, so I made do. The lighting is from lamps in a hotel room, so it was hard to edit for really true colors, but I tried to get as close as possible. The body was 13 mm long, wing 19 mm long. Female Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Spinner
View 6 PicturesI'm not sure of the species of this female spinner, and unfortunately I never found the associated males or duns to aid in identification. The egg-laying flight and fall of fairly large clouds of these females caused good rises of choosy trout for a week or so around early July on a large, cold spring creek in the northwoods. There is a distinctive stripe down the female's back, identical to that on this specimen collected a month later.
