Genus Lithophane (Pinions)
Lafontaine & Schmidt (2010) listed 52 Lithophane species in America north of Mexico.(1)
3 species were described in 2006 by Jim Troubridge (see PDF doc)
Adult: forewing usually gray to brownish with indistinct lines; live individuals at rest have an obvious and characteristic "square-shouldered" appearance

Larva: body usually green or grayish with variable pale or dark markings (see live images of 25 species by Lafontaine et al at CBIF)
much of North America south of the arctic but most species are restricted to northern United States and southern Canada
mixed and deciduous forests and woodlots; adults are nocturnal and come to light and bait
adults fly in spring and fall
In Canada, these are winter moths; they emerge in September and October, fly for a month, then hibernate and fly again in March and April. Larvae feed in spring and summer, pupate, and emerge as moths in the fall. [Tony Thomas]
larvae of most species feed on leaves of broadleaved trees and shrubs; a few species feed on conifers such as cedar (in L. thujae) and juniper (in L. boogeri); some larvae may also feed on other caterpillars, including their own siblings
They have been observed to feed on winter moth caterpillars and sawfly larvae (Sam Jaffe's observation, here, also B. Moisset, here)
Life Cycle
overwinters as an adult; one generation per year
