Cepaea
Cepaea is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Helicidae. The shells of species within this genus are often brightly colored and patterned with stripes.[3] The two species from this genus, the common and widespread C. nemoralis and C. hortensis, have been model species for early studies of genetics and natural selection.[4] They occur in Europe, although introduced populations occur elsewhere in the world.[2]

Like many Helicidae, this genus of snails create and use love darts.[3]
Species
For a long time, four species were classified in the genus Cepaea.[2]
However, molecular phylogenetic studies suggested that the latter two should be placed in the unrelated genera Macularia and Caucasotachea:[5][6]
- Cepaea hortensis (O. F. Müller, 1774)
- Cepaea nemoralis (Linnaeus, 1758)
- Cepaea sylvatica (Draparnaud, 1801), now Macularia sylvatica
- Cepaea vindobonensis (Férussac, 1821), now Caucasotachea vindobonensis
