Barklouse (Archipsocus nomas). Click on image to enlarge. Barklice

Scientific name: Archipsocus nomas Gurney and others
(Psocoptera: Archipsocidae)

Facts: Barklice are usually brownish and under 1/8 inch long. Adults have two pairs of membranous wings with the front wing larger than the hind wing. Wings are held roof-like over the body. Antennae are long and thin.

Barklice feed on fungi, algae and dead plant material. This species sometimes wraps large tree trunks and branches with webbing (as in this picture). The webbing causes concerns but is really harmless.
