Female Attenella attenuata (Small Eastern Blue-Winged Olive) Mayfly Dun

View 4 PicturesThis dun was badly damaged in transport and all its legs fell off, but I photographed it anyway because I wasn't sure I would fine more and it's an interesting species. Luckily I collected better specimens a few days later.

Collected June 5, 2005 from the Namekagon River in Wisconsin

Jargon Defined:

Dun: Mayflies have two adult stages. They first emerge from the water as duns (scientifically known as the subimago stage). They then molt into the spinner (imago) stage, in which they mate and die. Sometimes the word "dun" is confusingly used to refer to a brownish gray color in fly tying materials.
