The Japanese Beetle (Popillia japonica) skeletonizes the leaves of my grape vines. I have also seen a few on the potato plants in small numbers. They appear every year, certainly over the last three years.This year they are rather sparse and appear ill fed. My local control is to flip them off the vines into a pail of water, or simply squash between thumb and forefinger,or shake the vines on a windy day and they disappear.They are poor flyers.The damage is acceptable if they are not left to feed. They can skeltonize the grape leaves in an afternoon, since they are often in large numbers. Fifty to one hundred is not uncommon. Birds eat many when in the white grub stage.
