I saw a few Japanese beetles a couple weeks ago. They came right when the peonies were almost done blooming and didn't seem to bother those.

Haven't noticed any since then.

I have been seeing green metallic insects this spring/summer, including near the two Chionanthus I have. I can’t say with 100% certainty they’re EAB, but they sure look like it. There are no Ash on the property that I know of, but if the Fringe Trees die I’ll have a pretty good idea of what did them in

Yes, maackia, EABs damaged my fringe trees for yrs, tho this yr looks like less damage (maybe because there's so few ashes left for them other than suckers & saplings).

Maack, they are narrow and fast. The last ash I have has 60% dieback. By far the worst dieback this year

Japanese beetles regularly attack our climbing hydrangea and Fine Line buckthorns every year. Unless you want to hand pick (and even then half fly away), we’ve found the nuclear, insecticide option to be the only effective choice. Don’t love it but don’t want defoliated and weak or dead 10+ year old shrubs either.
