November - Snails

Snail-hunting is a great November pursuit, as fog and autumn rains provide the humidity they prefer. In years with wet summers snails flourish, and they will be seen in greater numbers than usual. Look in leaf litter in hedgerows and woodlands, gardens and even grassy path sides are great places to spot snails. Don't forget to send us in any sightings either via Living Record, or download a sightings form that you can print out and take with you.
