This species is native to Southeast Asia, but it has been accidentally introduced to many areas around the world.
The distribution includes:
The introduced distribution include states on the Gulf of Mexico, and it is widespread in Florida, USA.[3]
The width of the shell is about 12 to 16 mm with 5½ whorls.[3] The color of the shell is light brown, often with a single, apical chestnut band.[3] The shell is sculptured with fine, irregular growth lines and fine spiral striae.[3] The lip of the adult shell is reflected and the columella is partially covering the umbilicus.[3]
As an introduced species, the Asian trampsnail is often found in areas with tall grasses and high humidity. Typically this species is found in gardens, greenhouses, and similar habitats, sometimes retreating under logs or fallen branches.[4]
This species is often common with abundant old shells on the ground and among leaf litter, as well as on vegetation and on trees.[3] It is active after rainfall.[3]
Dundee and Cancienne reported that this snail can survive winters in Louisiana where the temperature can fall as low as 5-10°C.[4]
It feeds on a wide variety of plants including citrus[3] and is considered as pest in agriculture.[3] This snail is often exported by accident from Florida to other areas and thus poses a quarantine problem for Florida.[3]
This species of snail creates and uses love darts during mating.
