The JB have been pretty bad this year in NW Missouri - worse than the past 4 years, but not horrific. Wnen I lived in New England they were HORRIBLE. Had to rely on traps or you could forget Roses.
Here this year they did a lot of damage to Hibiscus and Roses. I enjoy squishing them.
Far worse this year has been grass hoppers - zillions of the little buggers and they do a lot of damage. Last year they practically trashed a Serviceberry over night.
