Yesterday on the Lower Madison I came across this mayfly on my vest.
I loaned my hatch identification book out and am having some trouble
identifying this insect.

Any help would be greatly appreciated.

Hey, Warren: Compare your pic to these:

I googled "March Brown" under google images. Are these the same animal?

This last pic;

might not be the same fly as yours, or as the others. Its labeled as a March
Brown, but it has three tails, a much smaller head, the leading edge of the
wings is much larger, and the markings are not exactly the same.

Even more interesting, I think, is the wide range of FLIES that are called
'March Brown'.
