Individuals contain both reproductive organs and are capable of self-fertilisation, although cross-fertilisation is the normal way. They live in quite varied habitats, from woodland and hedgerows, to gardens and allotments, where they can be serious pests. Mainly feeding nocturnally, or after rain, they consume various plants, and can do a lot of damage. Common and widespread throughout lowland Britain, absent from most of Scotland.
