I have often been fascinated by the behaviour of Snails coming together in groups for a while, then disbanding and going their own way. Why do they do this? Are they having a before dinner meeting to discuss which of my plants they're going to eat next d'ya think (Just kidding!)
Is it possble that they are all attracted to same spot by a particular chemical/scent?
Could the snails have found an environment that they are all ‘happy’ together e.g., I believe that you can encourage snails to congregate by placing pieces of wood, slate, stones, etc. (material that they can more easily move on?) around your garden. I would also imagine that congregation may help the snails keep a moist environment, especially during hot weather. I guess congregation aids in mating as well, which may be induced by pheromones in some types of snails.
