Common Barklice (Psocidae) - 66 Species, Identification & Facts

Blaste opposita

Identification: Two large black wing spots "opposite" each other (one on bottom, one on top). The only species in our area with that trait. Metylophorus noavescotiae has marks in these areas but completely different head marking and is larger. Ptycta

Blaste osceola

Identification: "...this may be Blaste osceola because of the smudge along vein Cua1 in the forewing. It is only slightly developed in the male, but it is present. The pterostigma is more extensively dark than in most of my specimens, but there is a

Blastopsocus goodrichi

Identification: Forewings unmarked, hypandrium with a pale triangular mark.

Camelopsocus hiemalis

Identification: Male with pale brown wash posterior to pterostigma and in cellCu2.

Indiopsocus ceterus

Identification: Very close to Indiopsocus texanus. Distinguished by subtle differences in the phallosome and subgenital plate. Was confused with Indiopsocus lanceolatus before that was recognized as a distinct species.

Indiopsocus lacteus

Identification: Dets. D. Young, male & female Type Locality: Texas, Hays, San Marcos: Thousand Oaks Loop (spmn in the INHS)

Loensia moesta

Identification: The black speckles all over the forewing are nicely diagnostic. When compared to the similar genus Trichadentecnum you will see that Loensia lacks the arc of 6 spots in the last 1/4 of the wing (one in the base of each cell). The very

Metylophorus barretti

Identification: a lot of variation in wing markings (per E. Mockford) Type Locality: Districo Federal, Mexico

Metylophorus purus

Identification: pterostigma completely clear, with white and black border; rectangular black marks between the eyes

Psocus leidyi

Identification: A row of three black dots running across the middle of the forewing; large black dot on the 'nose' and strong black dot over the ocelli also distinctive

Ptycta polluta

Identification: scalloped brown marks along the upper last half of the forewing (m1,m2,m3); markings continue down the center of the wing to the white and brown pterostigma

Trichadenotecnum majus

Identification: Six dark gray dots that form a backwards C in the last quarter of the wing, and the absence of fine black dots all over the wings suggests a female of this species. Can be found on sugar maples
