Typically, inch worms (true caterpillars) are the culprit of rose bud damage. These little insects look quite different from rose sawflies, at least to me. Regardless, inspection and hand removal is helpful, especially if you've only observed one or two.

How many roses do you have?

I've only seen the one so far, will keep an eye on it, though. I have 3 roses, all different kinds, I don't know what they are since they came with the house... If I post pics perhaps someone can ID them for me? Thanks!

Post a picture...we LOVE pictures! If you can't post one, then feel free to email them to me directly.

I have some pics just posted on the "roses" forum titled "id these roses". Thanks!

It's probably the tobacco budworm, and they're very difficult to control. The moth actually lays the eggs in unopened buds, so they're eaten from the inside out.

If you apply BT, it usually doesn't faze them because they're not eating the part of the plant that has BT on it.

Deanna, maybe not. The inchworm I saw was on the outside of the bud. I picked it off and have not seen another one. Maybe it was a fluke? It has also been rather colder than usual - I don't know how that affects the insect populations. Keeping an eye on it.
