Range Extent Comments
This species is Western European in origin (Cowie, 1999) but has been introduced into North America. It also occurs in the Azores, Australia, Europe, New Zealand, the United States, South Africa, Canada, North Africa, and Polynesia.
Occurrences Comments
Recently this species was found in several sites in the Hakalua Forest National Wildlife Refuge, on the windward slopes of Mauna Kea, Hawaii, Hawaiian Islands (Howarth et al., 2003) suggesting it may be much more widespread on Hawaii than originally postulated by Cowie (1997). In California, it occurs in 6 counties: Marin, San Francisco, Alameda, Monterey, Ventura, and Riverside (McDonnell et al., 2009). It was also reported for the first time in southern Illinois on the east side of the Mississippi River (Coppolino, 2008). In New York, Hotopp and Pearce (2007) report it from Madison and Wyoming Cos. as introduced.
Ecology & Habitat

Habitat

This slug is often locally abundant in pastures, hedgerows, plantation forests, and in native forests. It can penetrate deep into undisturbed forest from areas disturbed by humans (Barker, 1999).
