The row of spinules, absence of anal gills, and overall hairiness are all consistent with immature P. media. (The mature nymphs are cleaner, darker, and less hairy.)

I would also suggest altering the Paragnetina page to say that media is very important in both the East and Midwest. (media is probably the most widespread and commonly encountered large member of the Perlidae in the East. Due to its tolerance and adaptability it is often found in streams that have few other stonefly species.) The "accepted" (Stark, et al.) common names are Embossed Stone for media and Beautiful Stone for immarginata.

Posts: 1I'm working with some of these "hairy" Paragnetina from Vermont right now. I've found them difficult to key out because their gills are only somewhat branched, ocelli are difficult to see on many individuals, and the inner fringe of long hairs on the cerci is not present (probably due to immaturity). These pictures helped a bunch!
