Knockout pest

I have a pest chewing up the leaves of my Knockout Roses.
Could you please tell me what's
going on and how to treat.

Thank you for sharing the photos. On the second photo I see what appears to be a rose sawfly at the top of the photo, but it's not focused enough for me to be certain. Please take a look at the photo of a rose sawfly in this tipsheet, to verify that they are the same.

If they are a match, management options are included in the article. If they aren't a match, please let me know.
