The really pretty green ones are Emerald Ash Borer, and are a TERRIBLE pest that have killed a lot of ash trees. They fly away when you approach, so they aren't very catchable. Or, believe me, I would!Those the pretty green ones? Do you have so many? How does your garden compete with them? I know a lot of questions
These are Japanese Beetles. I hate them just as much for killing my hazelnut trees. So it makes me very happy to see the chickens eat them.
I find them on grape vines, my asparagus plants, and sometimes other plants. The grape vines are where I catch most of them.
