@futurebird _totally coincidentally_ before the following-on ant conversation popped up, I was about to send this photo of a tiny, <2mm arthropod frequently seen on wood here, to a friend.
Tiny and fast moving, it was only photographable using a general-purpose camera bcs it was caught in bright tangential sunlight scuttling around on smooth, wet cork-oak bark. It's [NOT!*] a woodlouse - Isopod - poss of suborder Oniscidea.
I'm bringing it in here bcs I just learned that similar species are closely associated with ants, who they "tidy-up" after. This tree has a seasonal ant city in it, but not since I've had the decent camera that took this photo.

@frankashwood Frank... do you know this one? Seems like someone you might know?
Hi all, this isn't an isopod, it is a springtail (Collembola) of the order Entomobryomorpha, probably an Entomobrya species. Some springtails are found in close association with ant colonies, just like some woodlice are, often pale ones which lack eyes.
Spring tails are kind of like ants for ants.
