Tho the photo is not real clear, I believe those are a mating pair of rose chafer beetles. The adult is considered a pest as it does feed heavily on plant foliage. It will eat a wide variety of plant foliage, flowers, and fruits including grapes, apples, peaches, roses, and other garden flowers and fruits.They are known to skeletonize roses. They are poisonous to chickens and birds when eaten.
Rose chafer grubs feed on the roots of grasses, weeds, and nursery stock.
Control can be done by covering small crops with row cover. Picking off adults and putting them in soapy water. Cultivation destroys eggs and pupae in the soil. It is especially if continued thru July. If large numbers of chafers are around, you can drench the soil with insect parasitic nematodes to kill the larvae. These are the nematodes that are effective on Scarab grubs. Rose chafers are good fliers, more can fly into your garden, so you will have to stay on top of them for a while.
Here is a site that shows more photos...this is the beetle correct?
