Tom, what do you think of
Fall Cankerworm, Alsophila pometaria, Wagner page 144. He says "Immediately recognizable by extra, half-sized pair of prolegs on A5." He could be looking at your image when he says that!

 
Right on again
This picture looks like the coloration and shape are in between the 2 pictures in Wagner. These "exceedingly variable" caterpillars are driving me nuts:-)
Thanks for reading through the text, and not just looking at the pictures in Wagner.
