Carabus auratus

This species is native to central and western Europe and has been introduced into North America.

The elytra, each marked with three broad longitudinal grooves, are an iridescent gold-green colour, as are the head and thorax.

Active during the day, it preys upon insects, snails, and worms, which it seizes with its mandibles and sprays with a digestive secretion before consuming it.

C. auratus can be welcome to farmers and gardeners, as it feeds upon pests such as the Colorado potato beetle.

The beetles' life expectancy is around two years; they overwinter under the shelter of stones or moss.
