''Deroceras reticulatum'', common names the "grey field slug" and "grey garden slug", is a species of small air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Agriolimacidae. This species is an important agricultural pest. == Distribution == The native distribution of this slug species is European.〔Horsák M., Juřičková L. & Picka J. (2013). ''Měkkýši České a Slovenské republiky. Molluscs of the Czech and Slovak Republics''. Kabourek, Zlín, 264 pp. (in Czech and English).〕 It is native to Europe, North Africa and the Atlantic Islands.〔 It occurs widely in Europe, but is more rare and restricted to cultivated fields in the southeast, particularly in the Balkans, and is probably absent from Greece and the Bulgarian mountains.〔 In the north and central European lowlands, Great Britain, and Ireland, it is probably the most widely occurring slug.〔 In northern Scandinavia it is scarce, and is mainly found as a synanthrope.〔 This species occurs in countries and islands including: * Great Britain * Ireland * Austria * Bulgaria * Czech Republic〔 Horsák M., Juřičková L., Beran L., Čejka T. & Dvořák L.
