White Grub
Polyphylla decemlineata (Say)

The larvae are white, C-shaped, up to 50 mm long, and have prominent brown head and legs. Adults are June beetles. Damage can occur throughout the growing season because of the one or two years spent in the soil as grubs. Damage occurs as tuber or root feeding by the larvae and is more prevalent in newly broken pasture or sandy ground where organic matter is abundant. Host plants: potatoes, grasses, corn, sugarbeets, ornamentals, fruit trees.
