    Orchards, gardens, hedgerows, parkland and open deciduous woodland.

    Finding the Moth

    Larva: in spun leaves folding down the leaf edge or in a flat spinning between two leaves. In Europe has been observed folding a leaf to form a pod.

    Adult: can be beaten from the foodplant by day and comes to light.

    Similar Species

    The combination of a pale forewing, two prominent black spots in the centre of the wing and an elongate black spot at the base of the costa (leading edge) make this a distinctive species. Darker forms are known on the continent.

    Other species which have the black spot or patch at the base of the costa are Gelechia hippophaeella, which is generally larger (wingspan 15-18mm as opposed to 12-16mm) and lacks the prominent spots in the centre of the forewing, and pale forms of Carpatolechia decorella which is generally smaller with black stripes rather than spots usually commencing further along the forewing.
