The nymphs of Mouse-like Barklice are sometimes found clustered together on tree trunks.
Mockford, in his handbook of Canadian and U.S. Psocoptera (1993) listed three described species in the genus: L. coloradensis, L. lugens, and L. sparsa. He noted that many eastern species are undescribed.
Mockford (1993) gave these key traits of the genus:
"Rs and M in hindwing joined by a crossvein. Distal piece of subgenital plate transverse, flat or slightly depressed on hind margin."
