Wingspan c.20 mm.
One of our commonest 'grass moths', this species flies in June and July and is easily distinguished with its one or two angled cross-lines and metallic golden fringe to the forewings.
By day it rests head-down on grass stalks, and is easily disturbed.
Its normal flight time is at night, when it is attracted to light.
The larvae feed on the stems of various types of grasses, usually at the base.
