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.

If the rose leaves are "skelatonized" where the veins are left behind then it sounds like Japanese Beetles. They love roses. The leaves will look like lace after being eaten with all of the green gone. If it is JB, then insecticidal soap will have no effect on them. That only works on soft bugs such as aphids, lacebugs, mealybugs. Organic methods of killing JB would be something strong like pyrethrins or neem oil. Grub control is also very important. There is a parasite of grubs called "milky spore" that eats the grubs and spreads through the soil to infect other grubs. It may take a few years to have very good control with this. Perhaps a multi-stage effort to kill out as many adult beetles as possible and also work on the grubs. Good luck!

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

Your ph is a little high and the roses may be re-acting to it as this can cause what looks like to me as a mild manganese deficiency starting. If it is, the leaves will go to a brighter yellow. I would give the roses a rest from any spray or fertilizer. Just water and see if the new leaves are normal looking. If they do go yellow then there is a foliar spray for mineral deficiencies. Don't give up on the roses as there is always some thing you can do to solve most basic rose problems.
