Hi, Karen,
Oops, the photos didn't upload. Are the holes along the margins and look somewhat knotched or scattered throughout the entire leaf? Primiarly along the edges is most likely vine weevil. Caterpillars cause holes scattered all over the leaf. Rhodos are susceptible to both. If caterpillars you can give a thorough inspection and pick them off. If it is vine weevil, it is more serious as you have to kill the larvae in the soil. Is your plant in the ground or in a container?
