This large weevil has numerous rows of minute pits (punctate) on the elytra as well as the pronotum. Otherwise the color is uniform shiny black. It is native to Europe and is a pest of many cultivated plants. The larval stage, a cream-colored grub, feeds upon the root systems reducing vigor and sometimes death of the plants.
