Moved
Moved from Neodiprion. Thanks, Dave. I hope to find an adult one of these days to verify that they're in the area.

Diprionidae
These look identical to European pine sawfly larvae, Neodiprion sertifer (Geoffroy). They could be confused with a couple other species, but they are so similar to N.sertifer it is safe to call them that.

European pine sawfly larvae?
These larvae correspond well to a description I found of the larvae of the European pine sawfly, Neodiprion sertifer Geoffroy, which is widely distributed and one of its hosts is Red Pine. Hatching occurs from early April to mid-May. The larvae in this photo appear similar to other larvae of this species that I have found on-line.
