I don't think so. This is one of several yellowish species I collected in September, and some of the others were much more widespread. I only found this species on one remote small stream in the Catskills. Surely it's found elsewhere but I don't think it's a major hatch.
Once I've got the rest of the pics online I'll try posting one each on the PA website and see if people can pick their "September peach fly" out of a lineup. Then I'll just have to figure out the species ID, which is no easy task since I've got mostly females.
