I only said the other day on a different thread that I have never seen it in my garden (I have lived here nearly 5 years)...spoke too soon and it has been on two roses now. I just did as Philippa said and wiped it off with my fingers (with gloves on!).
You're braver than me Sweetpea, don't do bugs well LOL! My lavender had quite a bit on earlier but the rain has washed it off
Just little froghoppers. Pretty much harmless.
I would also say harmless. I feel bad when I wash them off with the hose but my garden is not wild and everything has to earn its keep.
I read they were harmless too, it just doesn't look nice and I wouldn't want to be too close if I didn't have to be
they don't do any harm and are gone in a week or too, so why get excited. We need more biodiversity not less
I love the diversity and 99% of it is never going to harm anything.
