Hi,
I wander how bad it is for the roses?
You may have been looking at a large rose sawfly. The behaviour you
saw may have been egg-laying. If so, the larvae, when they hatch,
resemble caterpillars.
Here's the adult:

I have a pesticide-free policy in my garden, but I know that this isn't
for everyone. Treat the larvae as any other caterpillar if you want to
avoid damage to the foliage.
