    Foodplant and Larval Feeding Signs

    Unknown in Britain, but in the late 1990s was found feeding on leaves of Quercus spp (oak) in Europe during late summer and autumn. The larva has been located in mosses on tree trunks which were formerly suggested as a possible foodplant. However this habit is now considered to be for pupation rather than as a foodplant.


    Deciduous woodland.

    Finding the Moth

    Larva: unknown in Britain. Suggested as most likely to feed on oak in Europe although the larva has been found in mosses on tree trunks where it is thought they may go to pupate.

    Adult: rests on tree-trunks during the day and later comes to light where it has been trapped on one occasion in a light trap run at 14 metres up in the tree canopy.

    Earliest: 29th April circa 1900 (VC12) - the day and month were given but the year has had to be approximated and this may refer to a bred moth.
