    Scrophularia scorodonia (balm-leaved figwort) - see distribution map.  The foodplant is believed to be expanding its range and the moth may be able to take advantage of this (see record of the moth in Dorset).

    Feeds initially between spun leaves and, as the larva grows, below a folded leaf.

    Habitat

    Waste ground, sandhills, hedge banks and low cliffs.

    Finding the Moth

    Larva: feeds within spun leaves and, later in its development, underneath folded leaves.  It would be well worth searching for larvae where the plant occurs in coastal areas of south Devon and south Wales.

    Adult: comes readily to light.

    Similar Species

    There are no similar species in the British Isles.
