Unidentified sawfly larvae on yellow loosestrife

As part of my perusal of unidentified sawfly larvae in the BG gallery, I sorted the images into groups based on host plant. Earlier, I posted my summary of larvae associated with grass. An interesting result also turned up for yellow loosestrife (Lysimachia). Here are the two images, one from Maine, the other from Pennsylvania, that indicated yellow loosestrife (Lysimachia) as the host plant:

In April 2008, Eric Eaton noted on the former posting that Monostegia abdominalis is known to feed on yellow loosestrife. No images of that species were in the BG gallery at that time, but in August 2009, MJ Hatfield posted photos of the larvae and adults of that species that she indeed found associated with yellow loosestrife:

I am not qualified to say that the unidentified images are a match for the identified one, but I thought it would be useful to draw attention to this series of postings.

As with my previous notes for other species (listing in "See Also" section), I am providing these sorted images in hopes that Dr. Dave Smith or other experts will find them useful, possibly leading to identifications.
