pests and diseases

[Manouche]

Can anyone help.
Just spotted something I don't know about on the leaves of a shrub in my border.
Clusters of very bright red things ( they look like tiny little beads).
Is this some sort of fungus or could it be insect eggs of some description.
Really need help on this one.
Many thanks X

now i know i saw this over the weekend it was on the leaves of a deciduous tree but i was in  bit of a rush and didn't get chance to even take notice of tree type. I'm now racking my brain to remember where i saw it (hmm it might have been on the way to the grocery)

i think they are eggs and they looked like these: http://www.flickr.com/photos/zen/705858/

that's what I was thinking of, though they're actually galls rather than eggs. There'll be a tiny grub inside each one.
