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.)Reply
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.
