Just left of green stem ( 2nd photo down on left )you can clearly see a hole in the epipgragm. It is positioned directly above the pneumostome ( respiratory opening of the snail ) and admits air to enable it to breath during aestivation.

I was wondering if that were a breathing hole.

It is very warm an wet around here at the moment. Surprised to find any herbibore in aestivation.
