Description
Image:Carabus granulatus Linné, 1758 (2884924385).jpg
It is a small Carabus (length between 14 and 20 mm), winged and characterized by an elongated body which is not very convex and an enlarged thorax. The antennae and the legs are black, the upper part of the animal shiny, predominantly greenish bronze, green or occasionally black. The elytra are subparallel with "chain link" (longitudinal grooves with granules).
Biology
Carabus granulatus is one of the very few species of ground beetles that have not completely lost their ability to fly, only the mountain forms are short-winged. Nevertheless, the nocturnal animals generally remain on the ground, where they prey on insects, worms and snails. During the day they hide under tree trunks or stones. From autumn to spring, the animals often spend the winter together in tree stumps. The females lay about forty eggs. The larvae moult three times before pupating in the ground. The adult beetles hatch in autumn.
