The larvae are usually seen feeding in groups from late August to October and have a black head with a yellow collar. The body is a greyish green with rows of quite large, circular black spots running the length of the body.

I am not sure. It could be, they also look alike. I wll add it and still leave the ID as question, to see if somebody else has a better idea. Thanks, Jopy!
