I had a localized infestation of little, grey - brown beetles this year. They only got on a few plants, but put tiny, jagged, holes all around. They're about as big around as a pencil, and the holes are just about that size as well.
Zoom in on this pic (click on it , then click on it again) to see the holes. The problem was only in this bed and only lasted a short while (There are probably eggs all over these plants).
