Sounds like aphids. I have those on my dahlia's every year. hate them. Talk to your garden store and you should be able to get a dust for them. Sorry I can't remember the name of the one I have (I believe it is called Rotenone and is a broad spectrum insecticide - but quite nature friendly as I have bee's). I dusted some on my aphids the other night and then just hosed them off two days later while watering the plants. But if you take a small sample in a plastic bag the garden store can tell you for sure what they are.
