Blue-grey sawfly larva - Monostegia abdominalis

Blue-grey sawfly larva - Monostegia abdominalis
Allentown, Pennsylvania, USA
August 18, 2004
I saw the recent ID request for a spotted sawfly larva, and the comment that there is an expert around here - so let me submit this one I spotted a few weeks ago. My lysimachia punctata was crawling with them, and eventually skeletonized - the larvae disappeared, but didn't damage any neighboring plants. Would they have dropped to the soil, perhaps burrowed in to pupate? Another photo I took, of poorer quality, shows about 7 pairs of prolegs.
