The copulation has been studied in three Clausiliidae species [Cochlodina laminata (Montagu, 1803), Laciniaria plicata (Draparnaud, 1801), Bulgarica cana (Held, 1836)] from the Tula Region. All the observed snails exchanged the spermatophores. Each snail acted as a functional male and female in sequence, changing its role during the copulation. Spermatophore structure of these species is described. Cochlodina laminata reproduces during the entire warm season and deposits eggs on the fourth day after copulation at room temperature.
