July to September. Britain and Ireland. A medium-sized, brown moth with an antler-like mark on the forewing. Found in open grassland habitats.

This distinctive moth is distinguished by its cream, antler-shaped mark which varies in size on the forewing.  Black streaks on the forewing may or may not be present. Males are smaller than females and have feathered antennae.

The adults fly during the day, especially in the north and more frequently in the morning. They can be found feeding at flowers such as thistles and ragworts and can also fly at night. The larvae can be found from March to June, feeding mainly at night, hiding in grasses during the day. They overwinter as eggs.
