The mating of gastropods is a vast and varied topic, because the taxonomic class Gastropoda is very large and diverse, a group comprising sea snails and sea slugs, freshwater snails and land snails and slugs. Gastropods are second only to the class Insecta in terms of total number of species.
In some families of pulmonate land snails, one unusual feature of the reproductive system and reproductive behavior is the creation and utilization of love darts, the throwing of which has been identified as a form of sexual selection. [1] Gastropods reproductive systems vary significantly from one taxonomic group to another.
Cantareus apertus, [2] commonly known as the green garden snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae, the typical snails. Distribution
Usually they lay 20-50 eggs in rotting wood or below decaying leaves. Eggs are white and flattened, measure about 1 mm and hatch after 10–30 days. These gastropods reach their maturity only in the second or third season and can live 2–3 years. [3] Unlike many terrestrial snails they do not have a sex dart. [4]

The white-lipped snail or garden banded snail, scientific name Cepaea hortensis, is a large species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. The only other species in the genus is Cepaea nemoralis .
The reason why this happens only to mature snails is not yet known, but one hypothesis is that a mature snail will excrete a signal substance which attracts the P. ciliata larvae. Another hypothesis is that a mature snail has a change in the shell surface that makes it suitable for P. ciliata larvae to settle. The infection by this parasite ...
