Posts: 3Ok all, I am finding this hobie increasingly interesting and exciting. I no longer will just be guessing on the river, but actually selecting flies that best represent the actual bugs I am finding.

Here is another one from yesterday's trip, there are many of these flying around as adult, some size 14, others down to size 18, I grabbed one of the larger ones (just pushing size 14) and got some better macro pictures.

Thanks for the help in identifying this 'small' stonefly (that is my identification at this point anyway). Taken May 4th 2009 in the North Shore of Mass.

I apologize, but although I have re-sized these pictures (way down in some cases) I can not get them to display here. Links are posted instead.

Your stonefly is a member of the Taeniopterygidae, aka "winter stoneflies" or "willowflies." The smaller stoneflies that you saw might belong to another family, the Nemouridae, aka "spring stoneflies" or "forestflies." The emergence of some members of these two families overlaps at this time of year. (They look much alike, but the nemourids are generally smaller, emerge later, and have shorter second tarsal segments.)

BTW, per your previous thread, the #14 mayfly nymphs in the cup with your damselfly nymph are probably Hendrickson nymphs (Ephemerella subvaria).
