Insects of Cedar Creek

Order PSOCOPTERA

(Bark Lice)

The Bark Lice (245 NA spp) is a small order of relatively poorly known insects. Most are scavengers feeding upon lichens and fungi on trees or other vegetation. 24 families are recognized in North America, but few of even the major collections contain but a smattering of species. Perhaps 15 species belonging to five families have been collected at Cedar Creek. Serious collecting would likely quadruple this number. Some undetermined material remains, and the ID's provided below are largely tentative.
