Hi, I have noticed some wooly aphids in my garden, at least I believe them to be. Some are bright white fuzzy bas@&$? and some look little tiny armored/camoed bugs with just a couple of pieces of fuzz. I believe they collect the fuzz from the plant stems, is this correct?

I kill them manually(gloved finger squish maneuver) when I find them and also remove any fuzz from the affected areas. No major infestation yet. I do have quite a few preying mantids throughout my garden.

Should I worry about them? What type of damage do these aphids do?

Thanks for you help.
