#book louse

The psocids ( also known as bark lice and book lice ) are small to minute insects not often noticed, with large mobile head, threadlike antennae, and wings held tent-like over the body, in those species that actually have wings. Some of the minute wingless species are minor pests of stored grain, wallpaper glue, and book binding, hence the name booklice, but the rest eat fungi, algae, lichen and detritus on the trunks of trees, and hide under bark. One species was recently found to actually bores into wood. 

Last decade morphological and genetic studies proved that the parasitic lice actually evolved from within the Psocoptera, so the Psocoptera and Phthiraptera are now in the superorder Psocodea.
