carabus nitens

I cannot find to much info on carabus nitens but on ground beetles there is.Groundbeetles are often night hunters feeding on a variety of insects,groundbeetles are often considered good for gardes as they eat pest insects.Ground beetles are mostly between one or four cm,and some are brightly colored,like carabus nitens,it really jumped out when i turned the stone it was hidding under.Carabus nitens likes dryer places and is  considered endangered but can be locally abundant.From Galicia
