Mayfly - Leptophlebia cupida

Mayfly - Leptophlebia cupida
Bolton, Worcester County, Massachusetts, USA
May 12, 2005
Size: 14mm

Early Brown Spinner
Very nice photo.
Family: Leptophlebiidae
Genus: Leptophlebia
Species: (likely) cupida
Life stage: imago
Sex: male
Common name: Early Brown Spinner

Middle tail is much weaker, and slightly less than half as long as the outer two. Fore legs are dark, middle and hind legs are light. Fore wings are hyaline, lightly washed w/brown in stigmatic area.

If you'd like to attempt identifying winged mayflies yourself, take a look at my Adult Mayfly Identification page. It doesn't rely on couplets, but rather, accepts whatever observations you have, and narrows the choice, often to genus level.

Same as Black Quill?
It looks like Black Quill and Early Brown Spinner are just 2 names for the same mayfly. This one is a full adult(imago), while the other is newly emerged(subimago). The adult mayfly ID page is nice. I'll have to try it on some of my other pictures. Thanks for the help.

Tom-Yes, that is correct.
Yes, that is correct. One might assume a common name of Black Quill Spinner would have evolved. However, in this case, it apparently didn't. At least, I have found no record of one in flyfishing entomology references.

BQ spinner
Schwiebert mentions a pattern for a Black Quill Spinner in "Matching the Hatch." Caution should be used when applying many of the common names derived from "anglish", usually it refers to a pattern that imitates fishfood, rather than a specific insect taxon. In the west you could have a Black Quill hatch occur fishing wise that would not be L.cupida. Still, it can provide a handle to help in figuring out what bug you have. Trick is to shift gears between photography and phishing.

May mayfly
A male imago, I'd start with Ephemerillidae, it is a large group. The genus Ephemerella has about 100 species
