Looks like the damage a leaf cutter bee would do. If so, I don't think they are of real concern.

Yes, a leafcutter bee. So not a problem. Besides that, leafcutter bees are valuable pollinators. And as you likely have heard, we need all the pollinating insects we can get.

Wowza, you guys rock. Thanks for the zippy replies. I've just finished reading up on the Leafcutter Bee--what a curious insect. I've never heard of a bee living like this. But yes, you're right--we definitely need to support the pollinators! So I will leave be the bees and they can have all of my creeper leaves that they want :) I am going to keep an eye out, too--I'd like to see these guys in action.
Thanks again,

Actually, that might be a weevil. Go out at night and look for large beetles with long noses

Weevils leave very jagged edges on the plants they are feeding on. The very smooth, almost precise half moon shapes in the photo above are specifically characteristic of leafcutter bees.

Plus, leaf weevils are quite small.

Do you know what is eating my Virginia Creeper and is that causing it's to change color already in July.
