So far this year, I see no sign of black spot disease or bristly rose slugs (so far...), instead I've found an intruder that I've not seen on the rose bushes before: aphids (as usual, qualify that with a "what I believe to be...").

| Aphids on a hybrid tea rose bud (grrr!) |
 |
| Aphids on a knockout rose bud. |

| Aphid up close. |
I've found them on both rose bushes (hybrid tea and knockout), and they seemed to favor the buds, which made them very easy to spot and spray with
insecticidal soap. So far it seems to be doing the job.
I found this bit of information about aphids on a
site I found while searching around that might explain why they're here:
When days become shorter in the fall, both males and females are born. They mate, and then females lay eggs on stems or in bark crevices. The eggs overwinter and hatch the following spring.
Last year there were some aphids semi-infesting a mandevilla I had planted near-by. I let them live since they weren't doing too much harm - needless to say I won't be making that mistake again!
