Grass Rivulet

Perizoma albulata

Common & widespread in Britain.

Mainly nocturnal, but can been when flushed during the day.

The Larva is powerful, pale pink in colour with a brown head capsule.

The Larvae feed on the seeds of yellow rattle (Rhinanthus minor), as they ripen.

 In the name-type the ground-colour is white and the markings quite indistinct, light brown or grey-brown, the median band scarcely indicated except by transverse lines.

Our English race is less pure white, generally somewhat suffused with greyish or yellowish, but scarcely needs a separate name. 

Flies from May-July.
