Unidentified sawfly larvae - Taxonus pallidicornis
Virgin Run Lake, Fayette County, Pennsylvania, USA
August 19, 2018
Found on a shrub that I am not familiar with in a park in Westmoreland County, PA. It was eating the leaves and did not flinch when I moved the twig to get the pic.

probably Taxonus pallidicornis
Nearctic sawflies IV. Allantinae, 1979:

Larva.—One reared specimen is associated with Hopkins' No. 11388. The following information on the larva is associated with this number: "Bluish white dorsally, yellowish ventrally including legs and prolegs, dorsal and lateral surfaces with bloom or white powder. Black spotted, a dorsal row one spot per segment; a pair of subdorsal rows with three spots per segment; and a pair of lateral rows (above pleural fold) with two per segment. Head powdery large, dorsal one-third blackish blue; eyes in black spots at lateral areas of head and situated at the end of a bluish intrusion into the paler area below."

probably Allantinae
because there are 6 annulets and other subfamilies with 6 annulets (Blennocampinae, Nematinae, Selandriinae, Dolerinae) as well as family Diprionidae can be excluded based on the appearance or number of prolegs or host plant.

Plant photos?
Did you get any photos of the shrub so that it can be identified? Always a good idea, since sawfly larvae are host-specific!

Sawfly larvae
No, Charley, I did not. But, I can drive out to the site and take one. It was right by a gravel parking lot, so I remember where it was. Thanks!
