Anyone have a good mayfly dichotomous key or any others the like?

here is one I found that worked well to Id the march brown (my avatar) I was given the name of a few days ago. Knowing what I was looking for is cheating but it helps develop confidence when searching blind. I used dicotomous keys like this in reverse order in may Botony classes. Dichotomous key

And a simple anatomy chart?

here is one

I typically use this method, though not necessarily in this order. I have an excel file with all of the characteristics, and use the "sort" function extensively.

Generally, the characteristics I use first are:

1. Plain vs. mottled wing
2. Absent, small, or large hind wing.
3. Number of tails.

That gets me down to a workable half dozen or so genuses. Then decide between em by size, color, etc.

That key is from Roger Rohrbeck's website. http://www.flyfishingentomology.com/.
 
I seen some march browns toady along the Juniata in Huntingdon. Wasn't sure what they were until I seen pauly's photo. It looks exactly like it. Two tails, mottled wings, creamish colored body with dark rings, and the legs each one had 2 stripes on each leg.
