It looks like the same beasties to me - the RHS link says creamy grey-black, which looks about right.
It looks as though it's either pick off all you can find (do you have hens? they'll love them if you do), or spray/dust with something containing pyrethrum. Luckily there's no shortage of the latter, though I've no idea where your closest garden centre is out there.
Must check mine tomorrow...
Hope that's helped, please let us know what transpires.
