There were lots of these larvae on the underside of dogwood leaves at the edge of a river.

Moved from Dogwood Sawfly.

Apparently there are three spp. of these that feed on Dogwood, so I'm putting them at the genus level.

Thanks for the info Crystal. Now I know all the waxy white larvae aren't the same.

Dogwood Sawfly.
I think that these guys may actually be Dogwood sawflies, Macremphytus tarsatus, because they were found on dogwood and not anything in the genus Juglans. In addition, if you look at the structure of the wax on the other sawflies, you can see that it looks quite different. While older dogwood sawflies have a crazy spot pattern, young ones are typically covered in this waxy fur. Take a look at these pictures of the Dogwood Sawfly: http://www.forestryimages.org/browse/detail.cfm?imgnum=1398047
