Black bugs

Dear All,

I have a lot of black bugs on my dahlias and clematis. Can anyone please tell me what they are and how to treat them?

Thank you.

    Aphids aka blackfly. Wash them off with a string jet of water from a hosepipe. 😊

    They are probably aphids. Best to wash them off with a hose.
