Netted Slug – Deroceras reticulatum

This slug just loves to eat the bird food I put out, apart from my plants. You can see some probable slug eggs just to the bottom right of its back end.

Length 35 to 50mm. Also called the ‘Field Slug’ or ‘Grey Field Slug’, this is a fairly variable slug in colouration, but it usually has a pale cream body with a brownish mantle which has a netted appearance. It has a truncated keel. It produces clear mucus in large quantities, but it turns milky white when irritated. Similar to the Arctic Field Slug (Deroceras agreste).

A very destructive slug and hated by gardeners for it eats the leaves of many various plants and crops, including seedlings. Found in various habitats including agricultural land, parks and gardens. Common and widespread throughout.
