Mayfly Species Heptagenia pulla

These are sometimes called Golden Duns.

This elegant species may produce fishable hatches.

Heptagenia 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.
