Beet Carrion Beetle

(Silpha opaca). This destructive insect is frequently found in dead animals, but often its grub almost destroys the leaves of Beet and Mangold Wurzel crops. The grubs, which are black and shining, when full grown are from 1/3in. to 1/2in. long; the three segments next the head are rounded at the sides, but the other segments are sharp, and the tail segment has a sharp spine on each side. "When full-fed, the grubs bury themselves, and form cells at the depth of 3in. or 4in. below the surface of the earth, in which they turn to pupae, and from these the Beetle has been seen to come up in about the space of a fortnight or three weeks" (Ormerod). The Beetles are flattish, and about five lines long, brown-black, with a tawny down; eyes large and oval; horns club-shaped; body somewhat oval; wing-cases very flat, turned up at the outer edge, each case having three sharp ridges running along it; tip of abdomen dull red. Any manures or methods of cultivation that would stimulate growth in the plants, so as to permit renovation of injuries, would be found useful. If farmyard manure were applied to the soil intended for Beet in the autumn instead of in spring, it would lessen the risk of attack to the Beets.
