Chocolate-band snail Massylaea vermiculata Syn. Eobania vermiculata Syn. Helix vermiculata Massylaea vermiculata also known as Eobania vermiculata, common name the "chocolate-band snail" is a species of large, air-breathing, land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae, the true snails or typical snails. This species of large land snail is common in the Mediterranean area and it ranges from eastern Spain to the Crimea.

Picture: Andreas Gruber. Description The colour of the shell is very variable, whitish to greenish yellow, often with multiple color bands or spots; the lower side is frequently with two brown bands and whitish between lowest band and umbilicus. The shell has 4-4.5 whorls. The width of the shell is 22–32 mm and the height is 14–24 mm. The body of the snail is gray on the dorsal side and yellowish on the ventral side. Ecological Threat With Massylaea vermiculata having a long lifespan from 2 to 5 years an established population can continually grow. The long lifespan could make this species grow from a minor concern to a major concern for native gastropod species, garden plants and agricultural crops alike. Vineyards are very threatened with Massylaea vermiculata being observed on grape plants in their native range. Management This species is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce.
