The Riband Wave (Idaea aversata) is a moth of the family Geometridae. It is an abundant species in Europe, the Near East and North Africa, its distinctive outline familiar at lighted windows.

The species has a wingspan of 30–35 mm. The wings are buff or cream with dark fascia. Two main forms exist, equally abundant: One has darker shading between the central fascia (as in the picture), the other has not. The adults fly at night from June to August, occasionally later [1], and are attracted to light.

The larva is brown, tapering towards the front, and feeds on a variety of plants including bedstraw, chickweed, dandelion and knotgrass. The species overwinters as a small larva.

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