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 ...
A scarab beetle grub from Australia. The C-shaped larvae, called grubs, are pale yellow or white. Most adult beetles are nocturnal, although the flower chafers and many leaf chafers are active during the day. The grubs mostly live underground or under debris, so are not exposed to sunlight.

Not only do entomopathogenic nematodes affect their host insects, they can also change the species composition of the soil community. Many familiar animals like earthworms and insect grubs live in the soil, but smaller invertebrates such as mites, collembolans, and nematodes are also common.
