Do snails grow on trees?

In response to that question, our reader Bruce Berman from Boston sent this picture of a couple of Cepaea nemoralis on a sumac tree. The picture was taken on Lovells Island off Boston in August 2008. According to Bruce, the snails were about 10 or 15 feet (3 to 4.5 m) off the ground. Bruce also provided the following observations:
I often see them dormant on the trunks or on a curled leaf after a few days of dry weather in the summer. as winter approaches they are much more common on the ground in leaf litter, etc. When it is damp or wet, they climb to the terminal growth and eat like little pigs.
