Grass grubs are a widespread pest. The brown adult beetles (bottom) fly from October to January and feed on fruit trees and seedling crops. They lay eggs in pasture or lawns, and the larvae (top) hatch between December and March. The larvae eat plant roots through to September, killing off the grass.
