Explanation of Names
latipennis is Latin for BROADWING. lati meaning BROAD and penn meaning WING
one of four species in this genus in North America north of Mexico
34-36 mm wingspan
Adult - Forewing is gray with a narrow dentate median line. Hindwing is similar in color and pattern.(1) Rindge's description: Forewings pale gray with numerous scattered brown scales, producing unicolorous grayish brown; cross lines varying from obsolescent to cmplete, very slender; t. a. line tending to be obsolescent, when present arising on costa one-fourth distance from base, with basal tooth on radial vein, sharply outwardly curved in cell, then going more or less straight to meet inner margin about three-tenths distance from base; median shade band arising as brown spot near middle of costa, then becoming more or less obsolescent, apparently passing through or near small, dark brown discal spot, and going straight to inner margin; t. p. line arising on costa three-fourths distance from base, paralleling outer margin, thickened and with outward points on veins, more or less complete; s. t. line varying from being absent to very weakly represented, pale gray; terminal line dark brown, narrow or obsolescent at vein endings, thickened in cells; fringe concolorous with wing. Hind wings concolorous with forewings; intradiscal line rather broad, nebulous, straight; discal dot dark brown; extradiscal, s. t., and terminal lines, and fringe similar to those of forewings
Western North America from British Columbia south to California, especially west of the mountains.
Woodlands and forest.
Adults fly from May to August, but mainly in midsummer.
Larvae feed on various trees and shrubs, including Rhamnus purshiana, Holodiscus discolor, Sambucus spp, and Symphoricarpos albus.
In general, the moths from the Cascade Mountains tend to be slightly grayer and to have more clearly defined maculation than do specimens from the coastal areas of British Columbia, Washington, and central California
