What is it?
Like Stumblebum, I too have seen this but I always thought it was something that plant had secreted. I actually just saw this this other day. Next time I am going to have to check it out. Nice shouts by the way!

But what is it?
The bubbly stuff? Common name Cuckoo spit, secreted by the immature stages of sap-sucking insects known as froghoppers, presumably as a means of protecting themselves against predators.
The bug: Scientific names Various species but mainly Philaenus spumarius
Plants affected Many plants, including chrysanthemum, dahlia, fuchsia, lavender, rosemary, rose and willow
Main symptoms Blobs of white frothy liquid form on plant stems.
California common name is spittle bug
As a nurseryman in California we ran into them occasionally. I think they are another immigrant from the East Coast.
I never attempted to see the actual nympfs though.
The eye could be a rewarding subject at high magnification.

Not easy to get larger magnification when the crop is so extreme - the original is cropped to a degree, and to see just about ½mm or so is difficult, but I went in further Harold for you:

They are plentiful here in the UK this time of year - but largely ignored as they do little or no damage.
