Nymphomania?

This morning started brightly with a pair of Collared Doves at the end of my road - looking rather frisky. Great Tits were also singing their wee heads off as I wandered in to work. Spring is in the air. I must try summoning some more patch ticks by the power of blogging (come to think of it Yellow-browed Warblers have never been seen on my patch either).

I've been VERY busy logging all the footage we've taken over the past year. Over the summer I branched out into filming butterflies and dragons, so I find myself having to check the ID of every second insect. Butterflies I'm almost on top of; dragons and damsels are proving a little trickier. Between times I've also filmed rats, goats, deer, slow-worms, lizards, a good few moths, and extremely foolishly beetles. So here's my problem:

What on earth are they? My mothing chum David tells me they are likely to be Shield Bug nymphs. I thought they were simply orgying beetles. My eye-spy guide to insects isn't shedding any light. If anyone knows I'll be very grateful.
