Grey Garden Slug Deroceras reticulatum

To have or not to have a shell, that's the question... Having a shell means that you are a snail, not having one means you're a slug. Millions of years ago slugs had shells too. They lost them in the cause of evolution, but still have a remainder: chalky grains or even een chalky plate just behind the head. You can easily see the spot in the pictures below. They are of the biggest pest of all snails and slugs in the garden: the Grey Garden Slug. It will eat almost any plant and can be extremely destructive in rainy summers. It is smaller than the other slugs on this page, for it reaches a length of some 6 centimeters only. The Grey Garden Slug is also known as the Grey Field Slug or the Netted Slug.
