Forewing ground colour light greyish, a conspicuous black basal line connected to a short black line just before a reniform white patch, another short black line in the form of "V" just beyond the reniform patch.

Reddish orange, oval and flattened.

Young larvae are white, head capsule black, prothoracic plate white. The full-grown larva is pale green with a darker green dorsal line, head capsule yellowish green, prothoracic plate green with some brown laterally.

The eggs are oviposited in small groups of up to eight eggs on the twigs of the larval host plant.
The larva constructs a silken tube made by rolling a leaf edge downwards. At night, it leaves this tube to chew holes in the nearby leaves. Larvae can be found from May till early September.
Pupation takes place within a cocoon amongst detritus on the ground.
This species hibernates in the pupal stage. Pupae can be found from September till early April.

The species prefers Betula spp. and Tilia cordata, but it has been found, though much less frequently, on Carpinus betulus.

Mature Betula woodland, old forests with a lot of Tilia trees.
