Rose Blight

Question

What type of blight or bug eats on the foliage and leaves a clear spot on the leaves of roses?

Answer 1

The damage that you describe could be either a rose leaf hopper or maybe even a rose slug. On some occasions, I have seen aphids do this as well. I would imagine it is the leaf hopper, as the slugs usually leave holes instead of the clear leaf areas. All may be controlled using something like BioNeem by Safer or Ortho Rosepride Insect Killer.
