Finding the Moth
Larva: spins the shoots and terminal leaves into a tight ball-like structure, feeding within and sometimes moving on to make another spinning.
Adult: can be swept from amongst the foodplant, easily disturbed during the evening and comes occasionally to light.
A distinctive moth, particularly when fresh. The forewing generally consists of a brownish basal one-quarter outwardly bordered with an oblique black line of raised scales, an angled pale fascia at one-third, a mottled brown area in the central half of the wing and a paler section in the final quarter. Within this pale area is a black streak extending to just short of the apex. No other British species has this combination of markings.
Single brooded from late June to mid-August.
