Sage 
Family LIMACIDAE 
Slugs of this family differ externally from Arion of the previous family 
by the posterior position of the breathing pore in the mantle, the keeled 
back, posteriorly pointed foot, and absence of a mucous gland at the tail. 
They are native to Europe and adjacent parts of Asia and Africa; in 
addition some species of Deroceras occur naturally in northern Asia and 
North America. 
Milax gagates (Draparnaud) 
Plate Wi GC 
Animal of medium size, dark gray or black without darker or lighter 
bands. The posterior end is pointed, without a mucous pore; the back 
strongly keeled. Sides of body with distinct pedal and suprapedal grooves. 
The mantle is slightly granulose, but not concentrically wrinkled, its cen- 
tral portion bounded by a groove. The breathing pore is in the right pos- 
terior half of the mantle. Adults are 60-70 mm. long when extended. 
Distribution: British Isles, Europe, South Africa, Australia, Tasmania, 
Mediterranean countries, Introduced in many European colonies and in 
the United States (Pennsylvania, Virginia, Idaho, Washington, Oregon, 
and California). 
This ''Greenhouse Slug" is a destructive pest in gardens and greenhouses, 
It is largely subterranean in habit, burrowing in the soil and feeding on 
roots. 
Deroceras reticulatum (Muller) (= Agriolimax agrestis Linnaeus) 
Plate Tile 
Animal small, with a relatively short neck, moderately keeled tail, and 
prominent pedal and suprapedal grooves. It is whitish, cream, or flesh- 
colored, usually heavily mottled with gray or black. The mantle is con- 
centrically wrinkled, the breathing pore in its posterior half, Adults 
measure 35-50 mm, in length when extended. 
Distribution; British Isles, Europe, and adjacent parts of Asia and Africa, 

The ''Gray Garden Slug" has been introduced by commerce into nearly 
every temperate and subtropical country settled by Europeans and is very 
widely distributed in the United States. It is gregarious, and in countries 
where it is introduced is usually confined to the vicinity of towns and
