European Spruce Sawfly

Gilpinia hercyniae

Notes:

This sawfly larva was feeding off of a coniferous tree. It had quite the mimicry to blend into those needles! I believe it has caused some damage to the conifer, of which you can see at photo four. Notice all of I looked through Wagner's caterpillar book, but could not find anything with the same head. This was because it is a sawfly larva. BugGuide is trying to ID it at the moment.

UPDATE: BugGuide states this is not a moth or butterfly larva. It is a sawfly larva. They are trying to ID it at the moment.

Picture #4 is a picture of where he was. I took it as I went back to the location almost an hour later. I could not find him. I was using photo #4 to show the damage I think he did to the tree. He is quite difficult to ID; I can only find similar ones! None have the same head he does!

It must be hard to find since the caterpillar blend into those needles...
Where in picture #4 is he?

Thanks Karen! I just noticed that the needles have the same pattern as the caterpillar--two white lines along each side! I do remember...is this not characteristic of the Hemlock? Thanks again, everyone!
