caterpillar - Alsophila pometaria

caterpillar - Alsophila pometaria
Milton, Massachusetts, USA
June 8, 2005

All the images of Operophtera brumata we find on line
are greener than yours, but while searching we found an image of Alsophila , figure 9 that looks just like this. Rotate this image 180 degrees and it looks like a match! (Except yours has a redder head.) We wouldn't have guessed it from the green image in Wagner page 144, but it certainly could be the darker image he shows in the inset. Is this the same species as ?

 
Alsophila pometaria
I think the 2 caterpillars are the same species. There were thousands of them around on all the oak and cherry trees.
This year I've been hearing of an infestation of Winter Moths, and Fall Cankerworm Moths in eastern Massachusetts. So I would think this would be one of the 2 species, and Alsophila pometaria matches up.
Thanks again.
