Cockchafer

Agricultural land, grasslands, gardens, and woodland edges across Europe and parts of Asia.

Adults feed on the leaves of deciduous trees and shrubs; larvae (grubs) live underground and feed on the roots of grasses and plants.

They have a multi-year life cycle (3-4 years) primarily spent underground as larvae. Adults emerge in spring, often seen flying at dusk around trees. They are known for the loud buzzing sound they make while flying.

They pose no physical risk to humans but can be significant agricultural and garden pests as larvae can damage root systems and adults can defoliate trees. They serve as a food source for birds and mammals like hedgehogs.
