The Riband Wave (Idaea aversata) has a wingspan of 30–35 mm.
The wings are buff or cream with dark bands or cross-lines.
Two main forms exist, roughly equally abundant:
1. the typical form which has a dark band across all four wings (first 4 photos), and
2. the plain form, known as ab. remutata, which only has narrow cross-lines (5th photo).
The adults fly at night from June to August, occasionally later, and are attracted to light.
