Early Brown Spinners
Like most common names,"Early Brown Spinner" can refer to more than one taxon. They're previewed below, along with 3 specimens. For more detail click through to the scientific names.
Mayfly Species Leptophlebia cupida
These are very rarely called Early Brown Spinners.
Most anglers encounter these large mayflies every Spring in the East and Midwest. They are omnipresent in small portions, providing filler action in the days or hours between the prolific hatches of the early season Ephemerella flies.
See the main Leptophlebia page for details about their nymphs, hatching, and egg-laying behavior. This is by far the most important species of that genus.

This Leptophlebia cupida dun was extremely cooperative, and it molted into a spinner for me in front of the camera. Here I have a few dun pictures and one spinner picture, and I've put the entire molting sequence in an article.
