>>2151363In Pennsylvania, from China. Thought to have come here on some imported plants. Between them and the Lanternflies, the whole summer for me is shooting them off trees and killing them in any way I can. I think I'm buying a bug-a-salt and shooting the clumps of them in the trees while I'm out. Maybe I can get good with my slingshot, too. They leave egg masses, which are white or tan and flat, on trees. Scrape them off and put them in a bag with alcohol, or burn them. You can see some of the egg masses in this picture. The young ones are black with red or white markings.
