The surface of the cover wing bears longitudinal rows of large points, the spaces between which are narrower than the rows of points. Only the second is wider and more prominent than the others. Around the base of the wing covers there is a narrow, notched, black-colored edge, the side edge of the wing cover adjoining the outside is widest in the middle of the body. The pronotum is coarse and densely punctured, the spaces between them are granulated. The underside of the body is black, only the edges of the abdominal segments are yellowish in color. The antennae are colored yellow-brown at the base and darken towards the tip. The claws are longer than the third link of the tarsi .
Occurrence and way of life
The animals occur almost in the entire Palearctic , in Europe in the north to the south of Norway , in central Sweden and in central Finland , in England they are rare. The species was introduced into North America by humans. The fog shield beetles are often found on foxtail plants , on the undersides of which the females lay their clutch of 5 to 15 eggs in spring. The clutch is covered with a secretion. The larvae can appear as pests on young beet crops . The overwintering takes place as an imago in the litter.
