Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly NymphEphemerella (Hendricksons, Sulphurs, PMDs) Mayfly Nymph View 2 PicturesI found this specimen in the same collection as a similar one. Since I only have strange views of this one, it's possible that they're actually the same specimen and I somehow confused my picture-ordering and got the impression that they're different nymphs.
