I planted this rhododendron this past spring, and it's been doing very well. But just the last week or two I noticed these brown patches, and the hole in one of next spring's flower buds.

It almost looks like something is eating the outer green part of the leaf and leaving the inner 'skeleton'.

What is it, and how can I stop it immediately?? (I'm in Pgh. PA, zone 6.)

Thanks in advance for your help.
