Bark Louse Eggs and Adult - Graphopsocus cruciatus - Female
Seattle, King County, Washington, USA
November 18, 2006
Size: adult 5mm
Please don't frass...
I uploaded this because it shows a behavior that links this thumbnail with the barklice. I wasn't able to get any better photos, so I hope it's clear enough. I also observed this (female) creating a webbing-covered area for herself the next day. I don't have a photo of that, though.

Graphopsocus cruciatus
The wing markings and vein patterns on this species is unlike most other Psocoptera in North America...five dark black marks in the first half of the wing and a light beige "F" mark in the second half of the wing. Graphopsocus cruciatus; Family Stenopsocidae is thought to have been introduced in the 1930 to both the east and west coast from Europe or Asia. After quickly spreading up and down both coasts it is now slowly moving inland. Cool shot of egg mass. I have never seen that.
