Carabidae (ground beetles) 1, 2, 3, 4

Carabidae overview

There are over 25,000 species of Carabids (ground beetles) in 1500 genera world wide, 2,600 specie in Europe and over 350 in the UK. The fossil record goes as far back as the Permian. They are usually found on the ground and can run fast. The adults range in length from 3 - 36 mm, and are mainly nocturnal. Many of the European carabids are voracious predators of snails, slugs and many other invertebrates, so should be cherished by gardeners. In areas where the weather is cold, many species hibernate during the winter.
