The larva lives on Betula. When young it starts as a borer in the centre of a twig, later it enters the leafstalk and then the midrib of a leaf. When fully fed, it cuts out an oval case in which the larva drops to the ground.
The adults can be seen flying in sunshine around birch branches. They come occasionally to light.
