Answer 2

The adult white grub is a May or June beetle, but only the larva, “C”-shaped with a white body and tan or brown head, damages sorghum (Color Plate 3). The larvae feed on sorghum roots. A fully-grown larva is 20 to 25 mm long. Dark-colored, nondigested food can be seen through the smooth, shiny, transparent, last abdominal segment of the larva. Two rows of minute hairs on the underside of the last segment distinguish white grubs from similar-looking larvae. White grubs overwinter as larvae so are present in the damaging stage when sorghum is planted in the spring. Depending on the species, a life cycle may require one, two, or more years
