White spots with brown tips
By Rigga
United States 
On the lower surfaces of several mature tree branches - and on several tree types - I have found many small white spots (2-5mm dia) that look like insect "eggs". Some spots have brown tips on them.
The trees are in a small clump of relatively dense bushes and shrubs and do not get a lot of sun.
I am not an greatly experienced gardener and I know nothing of trees!
Should I be worried?
What can I do about them?

Thanks SBG,
I've just searched this site and found that soapy water is recommended - though I think I've caught it/them much earlier than the pictures I've seen here!
I'll update this question with what happens after I spray them.

this sounds like scale insect. they have a brown cap covering over the white eggs.
