([Denis & Schiffermüller], 1775)
Wingspan 12-16 mm.
The males of this moth have comb-like or 'pectinate' antennae, a feature unusual amongst the 'micros'. When viewed from certain angles, they also show a purplish metallic sheen.
It is a fairly common moth over most of Britain and Ireland, and flies during May.
The larvae mine leaves at first, later descending to the ground in a portable case and feeding on dead leaves. A number of deciduous trees and bushes can be used, but especially hawthorn (Crataegus).
