Appearance
The wingspan is 24–35 mm. When at rest, adults keep their wings overlapped and hugged against the abdomen, giving a long and narrow profile. The forewing is elongate, grayish-brown with two side-by-side dark oval spots near the middle of the wing, and another dark bilobed spot a little farther out. The hindwings are much broader. They are pale brownish-gray with a whitish fringe.
Food
The larvae feed on celery, grasses, lucerne, "Medicago sativa", "Polygonum", "Melilotus" and various other low-growing herbaceous plants. They have a black head. The abdomen is variably light brown to dark gray with a bumpy surface and sparse long hairs and a thin dark dorsal line bordered by narrow pale strip.References:
