Found under the bark of a dead pine tree

I suspect this is a barklouse nymph, based on the resemblance to this observation.

The thickness and segmentation of the antennae look like a reasonable match, and this one has plenty of debris. But I've never seen such a thing before and don't know for sure. Observed on a patch of lichen (Genus Lepraria) on the trunk of a living tree. I noticed the presence of the two bugs only when I was reviewing images at home, so I'm guessing about the dimensions based on the lichen forms.
