Rose bush
I have small holes in the leaves in a bush that was very healthy before we had a lot of rain. I don't see any insects but it resembles bug feedings.
It sounds like you have a night feeding beetle problem. Some beetles have long snouts that they use to poke into leaves/foliage of rosebushes and suck the juices out. I recommend either spraying all the rosebushes with a good insecticide or giving them a treatment or two of Bayer Tree & Shrub as per the label instructions. The Bayer also gives them some fertilizer to help deal with the stresses the bush may be going through due to the insects attack upon it.
