Ecology

Description and characteristics

Cornu aspersum has a rounded shell patterned with lighter and darker brown stripes, bands and mottling; some individuals have white flecks. Irregular wrinkles are visible on close inspection. In adults, a white lip borders the opening. The pattern varies between individuals rather than being uniform throughout the species.

It feeds on a wide range of plants, including vegetables, flowers, fruit plants and weeds. Mild, damp conditions favour activity. In cold weather it may bury itself and close its shell with hardened mucus; in dry conditions it also seals the opening to reduce water loss. It is hermaphroditic and lays white eggs in a nest dug into soil. Laying frequency depends on factors including temperature and humidity.

Mucus serves more than one purpose. This species produces protective secretions and two kinds of secretion from the foot: one adhesive and another lubricating. These different properties contribute to the animal’s interaction with the surface on which it moves.
