Barklice (Family Psocidae)
Barklice are small, chunky, big-headed, bug-eyed, long-antennaed insects, many of which have four wings. The front set of wings is longer than the rear set, and the wings are held tent-like over the body at rest. They are relatively common in the eastern half of the country and are often found on the trunks of smooth-barked trees. Because many BLs live in leaf litter or under loose tree bark, they generally pass their days unnoticed, as they have done since the Permian Era, some 250 million years ago.
