Glossy and smooth growing to 35-45 mm. Reddish head, greyish body with 2 parallel longitudinal lines in the middle region. Two small black spots are on the front and back of each segment, each bearing a bristle.
Hemispherical and ribbed milky white eggs are laid in irregular clusters on the leaves of hosts and on the soil surface.
Europe, Africa, the Middle East and Asia.
A vast range of horticultural and agricultural crops.
Early instars feed on leaves while later instars begin to feed below ground on roots of their host. Feeding on the leaves often produces windowpanes (just the lower epidermis remaining). External feeding results in fallen leaves and root feeding leaves obvious holes. Subterranean feeding by late instars causes toppling of plants.
Generations: 1-5 (climate dependent)
