Grasshoppers are usually the culprit for me when some plant has been chowed down. Can't say that I have seen them eating my butterfly bush though.

Because you can't see anything during the day, I suggest you look at 10 PM or so with a flashlight. The game is Search-and-Destroy!

Thats close Jackie but CHAENOMELES speciosa Iwai Nishiki blooms early spring to late Spring and this has flowers in October and the reproductive parts are different. Are there any flowering Quinces which bloom in the Fall? Seems like everyone knows what its not and not what it is. LOL Patrick

I buy the concentrated bottle, that you mix with water in a pump sprayer. Goes much farther then the premixed stuff. For the casual grower with only a few plants, I'm sure the premixed sprayer bottle will work for a season. Truthfully, I normally don't use Neem to get rid of beetles, though it does help with the JB if reapplied VERY often. Mostly I use it for aphids, thrips and Powdery Mildew, and any crossover benefit is nice, but not the main focus. I use soapy water knockdown for the Japanese Beetles, and take off any spotted leaves caused by them so other J. beetles aren't attracted to the pheromone they leave behind. I've noticed the dull brown beetles you are referring to, but they don't cause too much damage in my garden. When I've knocked them down in a soapy bucket, they tend to climb right out instead of drown. ?:-(? Glad they don't seem to congregate in my garden too much. Incidentally, I've been watching the scat of a nocturnal creature lurking around my gardens, and it's been full of Japanese beetle shells. I suspect a skunk, as some of my leaf mulch on the dahlia beds are scratched into the grass here and there. I am working on getting all the components for an electric fence to protect my bee hives (right next to my dahlia beds), as skunks are notorious for scratching the bottom entrances so they can eat the guard bees one at a time. Grumpy bees do not make good dahlia companions.
