popilla

Popilla, a genus of land snails in the family Bradybaenidae, is native to East Asia. These terrestrial gastropod mollusks are characterized by their coiled shells, which can vary in size and color depending on the species. Popilla snails are typically found in damp, shaded environments, such as forests, gardens, and undergrowth, where they feed on decaying plant matter, fungi, and algae.

The genus Popilla includes several species, with Popilla japonica being one of the most well-known. This species has a relatively small, reddish-brown shell and is commonly found in Japan, Korea, and parts of China. Other species, like Popilla theobaldi, are also found in these regions.

Reproduction in Popilla snails, like most land snails, involves the laying of eggs. They are hermaphroditic, possessing both male and female reproductive organs, though cross-fertilization is common. The eggs are typically laid in moist soil or leaf litter.

While generally not considered pests, some Popilla species can occasionally be found in agricultural settings, where their feeding habits might cause minor damage to crops. Their ecological role is primarily that of decomposers, contributing to nutrient cycling in their habitats. Conservation efforts for Popilla species are not widely documented, as they are generally abundant within their native ranges.
