AppearanceRose chafers are capable of very fast flight; they fly with their wing cases down. They pull their feet inside their legs and can push them out, if needed.
They feed on pollen, nectar, and flowers, especially roses. They can be found among roses on warm sunny days from May until June or July, and occasionally as late as September.
Rose chafers are found in southern and central Europe and in the southern part of the United Kingdom, where they sometimes seem to be very localized. They are a very beneficial saprophagous species . Their larvae are the insect equivalent of earthworms.
ReproductionThe larvae are C–shaped and have
⤷ a firm, wrinkled, hairy body,
⤷ a very small head,
⤷ and tiny legs.
The larvae overwinter wherever they have been feeding, which may be in compost, manure, leaf mould, or rotting wood. They grow very quickly and will have moulted twice before the end of autumn. They have a two-year life cycle.
They pupate in June or July. Some adult beetles may emerge in autumn, but the main emergence is in spring, when the beetles mate.
After mating, the female beetles lay their eggs in decaying organic matter and then die.
