They're living in harmony with the yellow jackets in the trees right outside my house. They are twice as long as your average yellowjacket (you know the kind that flies in your soda can at a picnic?) and all black with a white face pattern. The first time I saw one I thought it was a huge june bug, but then upon closer inspection realized it's a wasp/hornet of some kind.
My other question is I have something eating the leaves of my tiarella to the ground, but I don't have any Japanese Beetles this year. Any ideas? No, caterpillars, lots of ants though. I'm near Chicago in Zone 5.
TIA, Inattendue
