Birch Sawfly Larva (Arge pectoralis) - Arge pectoralis

Birch Sawfly Larva (Arge pectoralis) - Arge pectoralis
Chester County, Pennsylvania, USA
August 31, 2014
I know this is some kind of Sawfly Larva, but I don't know what the specific species is. I think it may be in the Arge Genus. The host Plant was a originally thought to be a Beech tree, but upon further inspection, was identified as a birch. The lighting was poor in most spots, so I placed the birch leaf on top of an oak leaf, where the light was actually shining. The lighting was still pretty poor though.

Argidae
Arge sp. None have been recorded from beech, so don't know what species it might be. Larvae are difficult to place anyway.

Yeah.
Hey, I was wrong about host plant. It was a Birch, not a Beech. In which case, it is Arge pectoralis. It looks very similar to those, so that would make sense.

Moved for expert attention
Moved from ID Request.

If you know what plant it was on, that could be helpful.

It was on....
A beech tree, I think. There was 4 of them. I would be more than happy to post a picture of the group. They were eating the leaves from the tree. The tree was quite young, so maybe it wasn't a beech tree. Actually, it might be a birch. Let me check.
