It has been introduced into North America, including Phoenix and Glendale, Arizona, and other areas Fresno, California[8][2] as a biological control agent, in hopes of controlling populations of the brown garden snail.

It grows to approximately 40–45 mm (1.6–1.8 in) in length and a width of 14 mm (0.55 in),[10] and upon reaching mature size, grinds or chips off the end of its own shell by moving its body roughly against hard surfaces, so that the shell takes on a decollate shape, tapering to a blunt end.

[10] Rumina decollata is a voracious predator, and will readily feed upon common garden snails and slugs and their eggs.

The snail eats plant matter as well, but this generalist predator is indiscriminate in its feeding and has been implicated in the decimation of native gastropods (including non-pest species) and beneficial annelids.

[10] Decollate snails are tolerant of dry and cold conditions, during which they burrow deep into the soil.
