Trichopsocus acuminatus
Who would have thought the lowly barklouse would ever receive so much good discussion. Similar to John I like to ID things by wing veintion. Xanthocaecilius is a smart idea, I even had to go back and check that it was not one of the two know North American species. While I am sure there are many tiny features that set them apart the simplest for now is size, Xanthocaecilius is small but this one is miniature.

I dug through Mockford's book on North American Psocoptera. I began by looking for psocoptera with a similar wing patters and then read the species descriptions. Your is distinctive with the long hairs along the veins and brown patches on the wings thorax and head. You appear to have found Trichopsocus acuminatus; Family Trichopsocidae. Great find, and new for the guide. I am glad you saved it from the pond, they are hopeless swimmers and should have known better.
