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 was just scouting, didn't like the look of the water, and as I was walking back to the car this little dun landed on my vest. Why can't they all be so easy to collect?

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.

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.
