    When to see it

    The adult moths emerge in June or July and like many of the group are rarely encountered, unless they are reared from mines collected in the autumn or winter.

    Life History

    The larvae feed on Holm Oak (Quercus ilex), creating a contorted gallery mine in the leaves. Usually there are several, larvae mining a single leaf. Mines occur from November through to April.
