A common species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc.

Like most pulmonate land snails, it is hermaphrodite and must mate to produce fertile eggs. Mating tends to be concentrated in late spring and early summer, though it can continue through the autumn. The snails often store the sperm they receive from their partner for some time, and individual broods can have mixed paternity. In Britain it lays clutches of 30–50 oval eggs between June and August. The size of the egg is 3.1 × 2.6 mm or egg diameter can be 2.3–3.0 mm. Juveniles hatch after 15–20 days. Maturity is reached when the shell reaches full adult form, which in France is after one year.
