Petal damage, what is causing it?

One variety (Passionate) which I bought new this year from Swan Island, has had bad petal damage on each of the first three blooms. Is this a disease problem? It seems to be limited to this one variety so far.

RE: Petal damage, what is causing it?

Steve, I have seen this kind of damage on hosta and dahlia leaves with baby pill bugs as the culprits, caught in the act. The small ones leave the translucent skin intact because they can't chew through it yet.

I haven't seen damage like this on blooms, though. My guess is its a tiny nocturnal bug that will soon grow up to take much larger bites out of your blooms if not stopped now.
