hmmm... i looked up leaf cutter bees cuz i have never heard of them before. i don't think we have them here but not sure. i'll have to go back and look at my roses again, i only remember seeing lots of little holes on the leaves. when i looked up the leaf cutter bees it shows they cut from the edge in on the leaves and it said about holes in the canes of the roses and i don't remember seeing that either. so i will go back see if i can get pics to show ya and see if i can find anything else. normally i'd say it was the japanese beetles but i haven't seen any and they usually hit all my bushes or most of them so i have to put traps out for them. this is only like 2 or 3 bushes of them so far. i'll have to see which roses it is too i think one of them is my wild one, not sure if the others r teas or my knockouts. if i can get good pics of what i'm seeing maybe it can help us narrow it down better. thank you so much for trying to help me i really appreciate it. i don't use chemicals on my plants so i have no idea what to use to help but i'd hate to have them destroyed. if by chance it is bees or something that is a good pest i don't want to hurt them either.
