The champions of this family are Leptophlebia and Paraleptophlebia. The large mayflies of Leptophlebia are on the water sporadically for a long time. The Paraleptophlebia flies are smaller but come in much more concentrated numbers.

Leptophlebiidae also contains several genera and species which are never mentioned in fly-fishing literature, either because they are too rare or because they require water too warm for trout.

Here I have a few dun pictures and one spinner picture, and I've put the entire molting sequence in an article.

I found this little Paraleptophlebia dun along a Catskill stream, but not enough of her brethren were emerging to get the early-season trout to rise.

After I took this photo, this specimen was swept out of this tiny pool into a riffle downstream, where I swooped it up with my aquarium net and brought it home to photograph.  See it up close here.

I can't remember where I read or heard these things (might have been on this site), but I want to make sure my vague recollections are not totally false. When Paraleptophlebia are mating, do they make exaggerated dives in clouds above the stream? If so, do they often end up in the water at these times or do they fall as spinners much later? Finally, when they emerge, do they do so at the stream bottom and then swim to the surface as duns?

Thanks for any help,
Shawn

This is one of the species that seem to be prevalent in our area of southwest NC. It emerges in March as I recall and again in October on certain streams. I would like to confirm that this next season.
