Heptagenia pulla (Golden Dun) Mayfly NymphHeptagenia pulla (Golden Dun) Mayfly Nymph View 8 PicturesLike most Alaskan mayflies, this one is tricky to identify to the species level. See the discussion section for an informative chat about this one's ID. The current leaning is to call it a fairly immature Heptagenia pulla nymph, but a case has been made for Heptagenia elegantula as well.
