Adult Leafmine

Life History

Like many of its congeners, this species is more easily identified by the structure of the leaf mine created by the larva. In this case, the foodplant is Beech, and the mine is a sinuous gallery with the frass forming a coil part way through the mine.

UK Status

Widespread in Britain, but probably under recorded due to its diminutive size. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as common.

VC55 Status

It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
