The mines are indistinguishable from those of Ectoedemia haraldi and Ectoedemia pseudoilicis, therefore DNA barcoding of the larvae is necessary.
The larvae create a strong contorted gallery mine almost completely filled with black frass. Usually there are several, often many larvae mining a single leaf. Mines occur from November through to April.

Flight periods

Adults are rarely seen but fly in June and July.
