I recently bought this rose and it has had several flowers on it, beautifully healthy and now the leaves are being eaten and it isn't looking as healthy as it was, any ideas, will add a photo, thank you.

The little caterpillars drop off if you move the leaves , so hold something underneath if you spot them & then step on the blighters. I agree with Bamboo ( rose sawfly).
