Images of many cosmopolitan spp. and those otherwise adventive in NA (7)
Range worldwide; a number of species cosmopolitan and spreading through the agency of man
Habitat barklice: always outdoors, in a wide variety of habitats; booklice often in homes
Food Barklice feed on lichens and fungi on tree bark, booklice are best known for feeding on starch in book bindings (5)
Life Cycle A few species are viviparous. Parthenogenesis is widespread, usually as thelytoky. Males perform a courtship dance accompanied with clicking sounds from their coxae. (9)
Booklice have 6 larval stages. (10)
Remarks The closest relatives of Holometabolans among extant insects (11)(12)
They often aggregate in herds, nestled under diaphanous silk canopies they spin from silk glands in their mouths. (9)
