Hi, I was just wondering if anyone could help me identify these little bugs that are crawling all over the stems of my sambucus nigra?
Many thanks

I think they are blackfly, especially as there is an ant there. Aphids, black and green are like cows for ants who milk them. Spray with soapy water. I don't know what they will do to sambucus, but they can ruin broad beans.
I have the same things on my sambucus ingra!!! They look like Beatles!!!!
There called sap Beatles.
Crikey No, but don't like the look of them . Will check mine tomorrow...YUK
These are sap beetles below
Sorry, I still think they are black fly aphids.
nothing else comes in clusters like that
