|Rose chafer beetles
Great numbers of rose chafer beetles, including Macrodactylus subspinosus, were first seen in central Minnesota during the second and third weeks of June. The beetles are tan to reddish-brown with bodies densely covered by dull yellow scales or hairs. Rose chafer beetles swarm on deciduous trees, shrubs, grapes, peonies, roses and other flowering plants shredding leaves and blossoms and destroying fruit. Adults live about one month. Larvae are small, long-legged, C-shaped grubs that feed mainly on the roots of grasses and tree seedlings.
