scientific name    Cabera exanthemata    

common name     Northern Wave

Foothill and northern boreal forests.

Adults fly in from June into late July.

A cream-coloured moth with fine, dark brown speckling and three (two on the hindwing) transverse lines. Looks like a slightly larger and duskier C. erythemaria, but lacks the yellow-tan overtones of erythemaria . Identification should be confirmed with genitalic structures, see McGuffin (1981). This species also occurs in Europe, where it is known as the Common Wave.

life history
In the Alberta foothills, adults fly from mid-afternoon until after dusk, and come to lights. The eggs are laid singly along the midrib of leaf undersides, hatching in 1-2 weeks. Mature larvae are yellow-green with dorsal and subdorsal stripes, pupae overwinter (McGuffin 1981).

Not of concern

diet info
Prentice (1963) reports 23 larval collections from willow (Salix spp.), and a single record from white birch (Betula payrifera).

Restricted to northwestern North America, occurring from Alaska south to Alberta and BC (McGuffin 1981). Also occurs in the Palaerctic region; the North American subspecies is bryantaria (Taylor).
