About Carabus clatratus Linnaeus, 1760
This species, scientifically named Carabus clatratus Linnaeus, 1760, is a ground beetle that reaches a body length of 25 to 36 millimeters, making it one of the largest beetle species found in Europe. Its body is copper-coloured, greenish, or glossy black. Large pits with copper or green iridescence are located between distinct secondary ribs on its elytra. Unlike most Carabus species, this beetle can have fully developed wings and is capable of flight. However, fully developed wings only occur in a small proportion of most populations, and most specimens have reduced wings. Macropterous (fully winged) individuals are likely completely absent from populations in Central Europe and Asia. This beetle is distributed across Europe and eastward through the Palearctic, ranging from Ireland to Korea and Japan, and reaching as far north as the Polar Circle. Most observations of this species come from Central Europe, Eastern Europe, and Siberia.
