So I noticed this yesterday, just before sunset. Also, all of these leaves are from one stem. Like a forest of leaves... but they are not red leaves. So I'm guessing not RRD?? In the first pic, the thick stem is where all of those leaves are coming from. In the second and third pic I slowly let the leaves fall back into normal position with my finger pointed at the same thick stem that can be seen from the first pic.

But anyways, should I be concerned for my rose bush, or my adjacent ones due to this bud being bored through, like this?

You can see it in the last pic. If you need another pic for clarity, please let me know. If I should deadhead this bud and slice it open to check for a critter inside, please let me know... thank you

I would not worry about a RRD. You have a few leaves only. That would be about 20-30% of what a RRD leaf forest looks like.

The damage looks old because it has dried out. It may have been a branch that was already dry and somehow broke (wind, etc.) or it may have been cut off by some pest. Without knowing which kind of pest did the damage, it is hard to protect the plant again. Monitor with more frequency and also monitor plants in that side of the property. If you have automated cameras that record based on movement in that area, you could try replaying to see what comes up.

I don't see anything there that looks like RRD.

And, though the good folks at Weeks DID bring it into CA, I haven't seen widespread evidence of it. Yet.

As to the hole in the bud, I wonder if that might be a BUD WORM . . .
=

Rose Budworm

The rose budworm (Pyrrhia umbra) is the larva of the bordered sallow moth. The rose budworm's body is covered with tiny black bumpy spots called tubercles. These caterpillars have two different color patterns; light olive green with longitudinal dark stripes bordered by a cream color or light olive green with a long stripe of white-orange going down its back. The adult moth form of the rose budworm has light golden tan fuzzy body with the same colored front wings and cream colored back wings.

Budworm Signs
Visual signs of budworm infestations include holes in rose buds or ovaries and tiny black seed-like droppings. Budworms chew their way into rose buds and eat the developing rose petals. This can damage a rose bud enough to prevent it from blooming. Flower petals that survive long enough to bloom will appear ragged or have multiple holes chewed through the leaves. The holes in rose petals may be lined with black or brown dying petal tissue.

Budworm Control
Budworm moths lay eggs on buds, terminal rose bush growth and blind shoots that are hidden in the rose foliage. If you detect the presence of budworm, remove all buds, terminal growth and blind shoots from the rose. Do not use broad spectrum insecticides, as they will kill off the beneficial insects, such as spiders, that eat budworms. Use organic, non-toxic pesticides such as Bacillus thuringiensis, or Bt, which is a beneficial bacteria that naturally occurs in the soil that specifically targets pest insects. Bt is sprayed on roses so that the budworm ingests it with the plant. Once ingested, the bacteria produces an paralytic endotoxin in the digestive system of the caterpillar and the insect dies from starvation within a few days.

This advice seems good to me. You might give it a try.

Ok. I did notice an olive colored caterpillar, the size of a rice grain. Probably a baby one. It was on a leaf though. I left it alone, I didn't know there were caterpillars that eat rose bushes. Except for the cane borers, but those are something different. I saw a tan moth yesterday. I will have to try and get a pic of it.

Aarrgghhh!

Thank you so much. I never knew what was doing this damage to my rose buds. I could never find the pest. A question; could be spinosad used ?

Oh, man. I did not see that, jerijen. It looked like it was plant debris or something not clear enough. I will reduce my caffeine intake and see if that helps me see right. Rolling on the floor laughing Rolling on the floor laughing Rolling on the floor laughing

@luis_pr what's a jerijen?
And what did you mean?

I guess the North American species is Pyrrhia Adela or Pyrrhia Cilisca.

I guess they finally made it to the west coast. Now I have to attract their predators.

Missing comma. It should have said: "I did not see that, jerijen."

Zuzu, thanks for the belly laugh! Way too few of those nowadays! Anyway, can you use spinosad on these little [email protected]#$s?

I think spinosad will kill them. I googled it. Lol.
I don't usually take google's word for it, but there were a lot of articles.
I don't have any experience using spinoSAD, so let me know how that works. When I get the resources, I may have to acquire some.

For now, I will try to eradicate these things by other means.

I bought some spinosad last year, and gingerly began using it. Something was eating up my morning glory leaves and I could never find the culprit. I used it and had good success with it. I usually don't bother with anything if I just have a ragged leaf or two. I only use stuff for serious infestations. The buds on my roses are fine now. I only had that problem earlier in the year.

The darn squirrels are eating my morning glory right now...

Grumbling

It's a seedling and they ate all of the leaves. It killed the other one. There used to be two.

I wish squirrels would eat the morning glory here.

It's like kudzu.
