Atropsocus
common barklice
Atropsocus is a genus of barklice in the family Psocidae, established by Mockford in 1993. It contains a single described species, A. atratus. Members of this genus are small, winged insects that inhabit bark and foliage surfaces, feeding on microflora such as lichens, algae, and fungal spores.
Blaste oregona
common barklouse
Blaste oregona is a species of barklouse in the family Psocidae. It was first described by Nathan Banks in 1900. The species is found in North America, particularly in the United States. Barklice are small, soft-bodied insects that typically inhabit bark, leaf litter, and other organic substrates where they feed on microflora.
Blaste quieta
common barklouse
Blaste quieta is a species of barklouse in the family Psocidae, first described by Hagen in 1861. It is found in Central America and North America. Barklice in this family are typically associated with tree bark and other woody substrates, where they feed on microflora including algae, lichens, and organic debris.
Caeciliusinae
Caeciliusinae is a subfamily of barklice and booklice within the family Caeciliusidae, order Psocodea. The subfamily was established by Mockford in 2000 and contains six recognized tribes: Austrocaeciliini, Bassocaeciliini, Caeciliusini, Coryphacini, Epicaeciliini, and Maoripsocini. Members of this subfamily are small, soft-bodied insects commonly found in association with vegetation and decaying plant material. The group shows substantial diversity, particularly in tropical and subtropical regions.
Graphopsocus
Graphopsocus is a genus of barklice in the family Stenopsocidae, order Psocodea. These small insects are characterized by their flattened bodies and broad, rounded wings that are held roof-like over the body when at rest. The genus includes both native and introduced species, with at least one species, Graphopsocus cruciatus, having established populations outside its native European range. Barklice in this genus feed on microflora such as algae, lichens, and fungi growing on plant surfaces.
Metylophorus
common barklice
Metylophorus is a genus of barklice in the family Psocidae, established by Pearman in 1932. The genus contains at least 50 described species distributed across multiple continents. As members of Psocidae, these insects are commonly found in association with tree bark and other woody substrates. The genus is taxonomically placed in the tribe Metylophorini within the subfamily Psocinae.
Philotarsus arizonicus
Philotarsus arizonicus is a species of barklouse in the family Philotarsidae, described by Mockford in 2007. The species is known from Arizona, USA. As a member of the order Psocodea, it is a small, winged insect associated with tree bark and foliage habitats. The genus Philotarsus is part of the infraorder Philotarsetae, a group of free-living barklice that feed on microflora including lichens, algae, and fungal spores.
Polypsocus corruptus
Corrupt Barklouse
Polypsocus corruptus is a species of barklouse in the family Amphipsocidae, commonly known as the Corrupt Barklouse. It is one of the most frequently observed barklice in North America, with over 2,300 documented records. The species belongs to the group of 'hairy-winged barklice,' characterized by setose wing surfaces. It occurs across a broad geographic range spanning temperate and subtropical regions of North and Central America.
Psocini
Psocini is a tribe of barklice within the family Psocidae, established by Hagen in 1865. Members of this tribe are small, soft-bodied insects commonly found on tree bark, foliage, and other surfaces where they feed on microflora. The tribe contains multiple genera and is part of the diverse Psocomorpha suborder. Psocini species are generally recognized by their wing venation patterns and body proportions, though precise boundaries between related tribes require detailed morphological examination.
Trichadenotecnum slossonae
common barklouse
Trichadenotecnum slossonae is a species of barklouse in the family Psocidae. It was first described by Banks in 1903. The species occurs in Central America and North America. Like other members of its genus, it is likely associated with bark and lichen habitats, though specific ecological details remain limited.
