Grey Pine vs Spruce Carpet.

 I've been looking at these two moths cross-lines and the various descriptions of how they differ and I'm struggling. I'm thinking the mainly brown one is Grey Pine Carpet and the greyish one is Spruce. Can anyone help?

    I think you are probably correct with these two, Mark. The two species can be very difficult (sometimes impossible) to separate, though, and the only supposedly safe way is a close-up view of the antennae of males. See:

    ok thanks Dave. I think I'd even struggle with the antennae!
