Synonyms and other taxonomic changes
Campaea perlata – (Guenée, [1858])
First described in 1858 by Achille Guenée as Metrocampa perlata
Explanation of Names
perlata is probably from post-classical Latin for "pearly" (the original description commented on its similarity to margaritata, whose name is based on the classical Latin word for "pearl" and no doubt means the same thing).
The classical Latin word meaning "carried through" is highly unlikely as the source for this name, although it's the only "perlata" in most Latin dictionaries.
Numbers
common to abundant
Size
Wingspan 28-51 mm; female much larger than male. (1)
Identification
Adult: wings and body pale greenish to grayish-white, often yellowish when faded; forewing antemedial and postmedial lines nearly straight, faint, darker grayish accented with white; postmedial line continues onto hindwing
[description by Charles Covell]

Larva: body with short hair-like fringes along ventral margin; when a larva is apresssed close to a branch, the fringes help break the outline of the body and make the larva nearly invisible
Range
Alaska across Canada to Nova Scotia; south to central California, Arizona and Colorado; in the eastern U. S. south to North Carolina.(2)
Habitat
coniferous, mixed, and deciduous forests and shrubby areas; adults are nocturnal and come to light, but in the arctic where summer nights are short or absent, adults fly during the day
Season
adults fly from May to September in the south; late June to early August in Alberta; July in the arctic
Food
larvae have been reported to feed on leaves of 65 species of coniferous and deciduous trees and shrubs, including alder, ash, basswood, beech, birch, blueberry, Buffaloberry (Shepherdia canadensis), cherry, fir, elm, hemlock, maple, oak, pine, poplar, rose, spruce, tamarack, willow [list taken from Handfield, 1999]
Life Cycle
two generations per year in the south; one generation in the far north; overwinters as a third-instar or fourth-instar larva, likely exposed on bark and branches
