Hi,
This looks like roseslug damage. See these pages and follow the links:

Good luck.
Hello:
I have some Sevin in liquid spray form. Do I spray the plant, the soil at the base or both?

The roseslugs are likely gone by now. Do you still see green worms on the leaves? Look at the underside of the leaves too. If you see them, spray. Otherwise, start checking rose leaves next May.
If you use sevin do so at dusk when pollinators aren't active. Sevin kills many beneficial insects.
Thanks.
