I found this on an unused screen porch. There is a little colony of them living on a piece of paper with what looks like scattered bug parts.
They seem to be eating the "bug parts" and I have seen them push another away on approach.
They scoot around quickly. They appear to be quite flat, but I was not able to get a lateral view.
This looks to me like an immature, I'll post another one that looks more mature.

Note the red stripe and yellow eyes. I haven't seen these features on the Psocids in the guide.
