Light Brocade

The wingspan is 36–41 mm. The species is very similar to Lacanobia contigua. The forewing ground colour is red brown, violet brown, silver grey and dark brown. The reniform and orbicular stains are large and partially reddish tinted. The basal dash is very dark and striking. The midfield and extreme marginal area also stand out also dark, while the inner marginal field is grey brown to silver grey. In the subterminal light wavy line, a large W character is visible, which serves as the basis for the Latin name w-latinum. The hindwings are grey brown and mostly without markings but slightly darkened at the edge, only the dark veins emerge more clearly. The flat, hemispherical egg has protruding, wavy ribs. It is initially yellowish green, later whitish or grey with crimson spots on the top. The colouration of the caterpillars varies from greenish or yellowish to brownish grey. They have an indistinct dark dorsal line with dark slashes. In addition, they show bright lateral stripes and legs, as well as black spiracles. The head has two distinctive vertical, black stripes. The dark red-brown pupa has a small, shovel-shaped cremaster with two tips constricted at the base.
