Status:

This is one of the largest and most striking of the world's slugs. Considered native to Europe and parts of Africa, it has been widely introduced in the U.S. and other parts of the world. Occurs around developed areas throughout North America. Exact arrival date unknown, but recorded as common in Philadelphia by 1867 (Norden & Williams, 2015).

Relationships:

Feeds mainly on vegetable matter, but has been reported to occasionally be cannibalistic or carnivorous. Documented preying upon emerging Magicicada septendecim during Brood X emergence in 1987 and 2004. (Norden & Williams, 2015)

There are 475 records in the project database.
