Foodplant and Larval Feeding Signs
Scrophularia scorodonia (balm-leaved figwort), see plant 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).
Has two broods, feeding from October to early June and July to September, initially between spun leaves and, as the larva grows, below a folded leaf.
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.
There are no similar species in the British Isles.
Double brooded from late May to early July and September to mid-October.
