This species has not yet become established in the wild in the US, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore, it has been suggested that this species be given top national quarantine significance in the USA.

This slug is most easily recognized by the black speckling on its mantle or hyponota. The body length can reach up to 60 mm.

This species may be found in undisturbed environments as well as in agricultural settings, where it may be regarded as a minor pest.
