Probably a young perlodid
This immature stonefly nymph is either a perlid or a perlodid. I'm leaning toward a perlodid ID. There are no branched gills (characteristic of perlids) to be seen at the leg roots, although such gills may not be as obvious in earlier instars. The rear wingpads are more elongate than is typical of young perlids, and young perlodids often appear to have oversize heads.
