* I wasn't supposing they were active now, I was just trolling for some
species that might have done the feeding in the fall, and not left any
shells on the surface, either because they were slugs, or because they
weren't dying on the surface.

* no, they wait until the stems have died, and then swarm up them,
stripping the stems down to the white core. In the fall, we use the
presence of the stripped stems as evidence that the Cepaea have spread
that far from the introduction site.

In the Ceapea line, I'd like to hear of any situation where Cepaea eat
live green previously-unmunched vegetation. We have a neighbour who says
they perforate her Hosta plants, but we suspect Deroceras reticulatum is
the real culprit, and the Ceapea are just cleaning up after the slugs.

Incidentally, the co-ords I gave in the original message was the wrong
waypoint, the actual site is 44.657799N, 75.816458W.
