An obvious indication of infestation is the presence of birds, such as crows, peeling back the grass to get to the grubs.
The grubs develop in the earth for three to four years, in colder climates even five years, and grow continually to a size of about 4–5 cm, before they pupate in early autumn and develop into an adult cockchafer in six weeks.
