obvoluta, common name the "cheese snail", is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Hygromiidae, the hairy snails and their allies.
The main distribution zone of this species extends from north western Spain across France, Switzerland, Liechtenstein, Belgium, Luxembourg, the Netherlands, southern and central Germany, Austria, Czech Republic, Slovakia, Poland, Hungary, Slovenia, Croatia, Italy, Bosnia and Herzegovina and Serbia.

The average life span of "
obvoluta" is 2 years, with a maximum of 3 years. The activity period stretches from April to November; daily activity is concentrated in the early morning and at night time. Mating can last for 2–3 hours. There are two periods of reproduction, the first one in spring (April–June), the second in autumn (August–October).
The eggs are laid in clusters of 9-27 per clutch in rotten wood and are covered with a mucus layer for protection. Juveniles hatch after 14–31 days of incubation time, and reach maturity after 140–624 days. The spring generation may reach maturity in the same year, while the autumn generation has to overwinter as immature snails. "
obvoluta" spends most of its lifespan near and in fallen tree trunks, which provide places for egg-laying, feeding, shelter in daytime and hibernation sites in winter. In the case of populations that live in milder, oceanic climates such as Great Britain, snails can also hibernate within leaf litter.
