The Specimen

Ephemerella aurivillii Mayfly DunEphemerella aurivillii  Mayfly Dun View 9 PicturesThis dun hatched in my aquarium on July 16th from an easily identified nymph collected on July 10th, and it molted into a spinner after I photographed it. The beautiful spinner form is listed as separate specimen. I forgot to photograph the dun with the ruler, but naturally his size is pretty similar to what it was as a spinner.
Collected July 10, 2011 from Nome Creek in Alaska

Wow, that's our boy. Definitely pink, eh? Answers a lot of questions for out West.:)
