The Japanese beetles (Popilla japonica) have arrived in their usual huge numbers. This one is enjoying my grape vines’ leaves, and you can easily see why their feasting is not welcome to most gardeners. The Japanese beetle arrived in the US around 1916 from Japan. In Japan it is kept in check by an insect predator not found in America. Suburban gardeners annually decorate their gardens with colorful beetle traps which are suspected to attract more beetles than they actually catch!
