Overview

Comprehensive Description

General Description

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 Cycle

Life Cycle

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).

Common Wave

The Common Wave (Cabera exanthemata) is a moth of the family Geometridae. It is found throughout the Palearctic region and the Near East.

The wings of this species are white, heavily spotted with tiny yellowish dots, which give it a buffish appearance. The wings are marked with narrow brown fascia, three on the forewing, two on the hindwing. The wingspan is 30-35 mm. One or two broods are produced each year and adults can be seen at any time between May and August [1]. This species flies at night and is attracted to light.

The larva, green with yellow rings and black and purple spots, feeds on alder, aspen, beech, birch and willow. The species overwinters as a pupa.

Notes

  1. ^ The flight season refers to the British Isles. This may vary in other parts of the range.
