This common name refers to only one species.

Mayfly Species Ephemera varia

These are very rarely called White Duns.
This is an excellent hatch of a different character than its Ephemera brethren. Rather than emerging in a flurry of activity within a week, the Ephemera varia flies may last for more than a month in a single place.

Female Ephemera varia (Yellow Drake) Mayfly DunFemale Ephemera varia (Yellow Drake) Mayfly Dun View 7 PicturesThis yellow drake dun hatched out of my aquarium over a month before her brethren in the wild are slated to emerge. She seems a bit small, and that might be the reason.

Female Ephemera varia (Yellow Drake) Mayfly SpinnerFemale Ephemera varia (Yellow Drake) Mayfly Spinner View 6 PicturesI found this female spinner ovipositing in a small stream. She came along while I was playing a trout -- every good bug seemed to do that last night! I didn't have my bug net, so I caught the trout in my landing net, released the trout, and caught the mayfly in my landing net. Her wing got a bit messed up from that.
