Spotting

Description:

This is such a small mite - smaller than a grain of rice. I only spotted it as a ladybird was chasing one of them for a snack - they were in the door jamb (uPVC - not wood). Unfortunately I don't have a clearer image. It seems to have three pairs of legs, one set of antennae, two black eyes, a long body (relatively speaking) with what looks like a division - perhaps for wings - or it's digestive tract?
