Bucculatrix albedinella

Wingspan about 9mm. A tiny, white and buff species with slight tufts. The larva mines the leaves of Elm.

Adult Leafmine

Areas where Elm is present.

The moths fly in June and can be found resting on the trunks of the foodplant, Elm but it is most often encountered as a larval mine on the leaves. They are distinctive due to their 'divertacula' - small offshoots from the mine itself.

The pupal cocoon is not ribbed, unlike most other members of the genus.

Distributed in southern to central and north eastern England. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.

Occasional in Leicestershire and Rutland, increasingly recorded from leafmines on Elm.
