The European chafer has a 1-year life cycle. The imago, or adult beetle, stage is quite short, lasting 1–2 weeks. The adults come out of the ground in late spring and mate in large swarms, usually on low trees and shrubs. The beetles are most active on warm, clear nights when the temperature is above 19 °C (66 °F).
The larvae, known as "chafer grubs" or "white grubs", hatch four to six weeks after being laid as eggs. They feed on plant roots, for instance potato roots. 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 ...
Chafer beetles also act as pollinators for many species of flowering trees. Grubs of this species, which reach 40–45 mm long when fully grown, live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens, and in grassy amenity areas like golf-courses. The grubs can ...
Holotrichia is a genus of beetle in the family Scarabaeidae, which are well known as "chafer beetles" or "white-grubs" for their white larvae that are found under the soil where they feed on the roots of plants.
Females lay their eggs on rotting wood on the trunks of old trees, especially ancient oaks. This species spends most of its life as a grub, living in the rotting wood of old trees, mainly willow, poplar, oak and fruit trees. Larvae grow to a length up to 48 mm and take two years before pupating.
