Hedgerow.

A good day-no rain just cloudy.  A good camera club social meeting at a local cafe this morning,  before having a look in a hedgerow to see what I could find.  Over just a short distance there was a variety of plants now 'shedding' seeds and 'sticking to other plants,  but I noticed this snail on a stem.
It caught my eye because of the two-tone shell.  Why two-tone?
