Rose Chafer
North America.


Adults chew on flowers, fruits, leaves, but are usually damaging only when very numerous. When this happens, they can cause serious harm to developing grapes, ripening cherries, and buds of roses.

Destruction is more severe in areas with sandy soils. Adults also may attack strawberries, dahlias, irises, hollyhocks, peonies, and vegetables. The larvae do little noticeable damage and feed on the roots of grasses and weeds.


Adults are reddish brown beetles, with wing covers bearing small, yellowish hairs; the body is black on the underside, 1?3 inch long. Larvae are small white grubs found in the soil.

Crime Prevention

` Where infestations are severe, protect small plants with floating row covers until July to prevent adults from laying eggs.


` Cultivate soil until early June to eliminate pupae.

` Spray pyrethrins as a last resort, if large numbers of chafers are present.
