Ephemerella (Hendricksons, Sulphurs, PMDs) Mayfly NymphEphemerella (Hendricksons, Sulphurs, PMDs) Mayfly Nymph View 5 PicturesThe striking coloration of this Ephemerella nymph earned it a turn under the camera lens. It has a different look than others I've collected, but I still might tentatively guess it belongs to the widely variable (and ironically named) invaria species.
