Ealeagnus Covered In Fleas ???

I see lots of Ealeagnus bushes around and this time of the year they are covered in some small flies which look a bit like fleas. They even jump when you touch them. I have loads of pictures of them but don't know how to upload pics.

Does anyone know what these things are ?

Also if anyone could tell me what to to to get a photo on I would be grateful.

 

If you do a search on Flea Beetles I think you will find that this is what your mystery bugs are!
