Bucculatrix demaryella is a moth of the Bucculatricidae family. It is found in most of Europe (except the Iberian Peninsula and parts of the Balkan Peninsula), Russia and Japan (Hokkaido, Honshu).[2]

Mined and gnawed birch leaf

The wingspan is 8–9 millimetres (0.31–0.35 in).[3] Adults are on wing from May to early June in one generation per year.[4]

The larvae of ssp. demaryella feed on Betula nana, Betula pendula, Betula pubescens and Corylus avellana,[5] while the larvae of ssp. castaneae feed on Acer species and Castanea sativa. They mine the leaves of their host plant. The mine has the form of a short, full depth corridor, often along the midrib or a thick vein. Most of the mine has a thick frass line. The larvae leave the mine and engage in window-feeding. Later, it starts eating holes in the leaf.[6] Larvae can be found from June to July. Young larvae are pale yellow with a darker head while older larvae are grey green. Pupates takes place in a greyish ochreous cocoon spun amongst debris.
