There are several species of beetles referred to as chafer beetles. The adults come in a variety of colours and sizes between 10 and 25 mm in length. The larvae are known as white grubs (15-35 mm long), often found in soil or compost.
While chafer beetles can cause feeding damage on flowers, fruits and leaves of almost any plant, the soil-living white grubs feed on organic material. Some species can however cause serious damage on roots, corms and tubers.
