Maybe
Maybe sawfly larvae, were any coiled up under the leaves like this? Do you have any close-ups of just one, maybe showing the legs?

Gray larvae
Thank you for your quick responses. Sorry about image quality. This year I'll do better. Although very similar in appearance and the fact that these guys curl up if they sense movement, they are very, very pale gray-from a foot out they look nearly white. That is why I call them ghost worms. Could the color difference be the result of what they are eating? I just did a search on sawfly larvae and they look just like those in the 8th row down, extreme right column. So, these are bad guys? What would you suggest to get rid of them?

I'd agree.
Monostegia abdominalis is known to feed on yellow loosestrife. Now, if we could just get them to eat PURPLE loosestrife! LOL!

worms
Hi; I'm glad you asked this. We have exactly the same problem a little North of you in Quebec, now I know what it is. I sympathize, they really ruin the plants.
