Biological Notes

Generally nocturnal, which results in few sightings and therefore often thought to be a less common species. Mates late summer and eggs laid from late summer to winter. Juveniles most common in late winter and spring.

Geographical Distribution

Originally thought to be native to Europe, particularly the Mediterranean region, but now commonly found as an agricultural pest worldwide: Great Britain, Ireland, Ukraine, South Africa and China.


Usually associated with disturbed habitats. Often found around human habitation.

Damage Caused/Symptoms

Voracious appetite for seedlings and vegetables. The species has been observed to feed around the trunks of mature banana trees, resulting in them toppling.

Crops at Risk

Ornamental plants, field vegetables, stored fruit and vegetables. Commonly found as a pest in greenhouses and polytunnels.

Impact and Severity

Young slugs rasp away the surface of plant leaves. Adults reduce the saleability of commercial plants by chewing holes in leaves and leaving slime trails.

Prevention and Control

Trapping may reveal the presence of this species. As with many other species of slugs and snails, the combination of cultural and chemical control usually provides the best results.

Natural Predators

Birds, beetles.
