Pennsylvania Barklouse for ID - Blastopsocus lithinus
Off Rt. 183 near Appalachian Trail, Berks County, Pennsylvania, USA
September 7, 2020
Size: 5 mm
In trying to photo Psocodea, I have noted their annoying oftime habit of wandering in short start and stop spurts. At least they mostly stick around; this one uncharacteristically "flew the coop" so there is just one image for ID.

Sweet!
This is Blastopsocus lithinus, female. The "Preclunial abdominal segments 2-6 each with a purplish brown ring" (Mockford's book). In your specimen, the banding has fused to some extent. I never take images in the field. Don't know how you manage it!
