Species can be difficult to distinguish from one another upon cursory examination, because individuals of a species can vary in color and there are few obvious differences between taxa.[3] The color of an individual can be influenced by its diet.[4]

Some Arion are known as pests, such as A. lusitanicus auct. non Mabille (= A. vulgaris), which damages agricultural crops and ornamental plants, and A. rufus, a familiar garden pest.[5] Arion slugs are often transported internationally in shipments of plant products and mushrooms.[6] Arion slugs have been identified in North America and Australia as invasive species, altering the plants of ecosystems through seed predation and competing with native slugs. [7]

Etymology

The name Arion is from Neo-Latin, from the Greek areíones, a “kind of snail or slug.”[10]
