22 species. Slender medium sized moths with delicate elongated legs and abdomen, readily recognised by having their wings cleft into lobes. All species in our area have the forewings divided into two and hindwings into three lobes. They rest with their wings held at right angles from the body and have a weak fluttering flight. Imagines fly in the evening and come to light and can sometimes be disturbed from vegetation in the day.

Their larvae are stout with tufts of short hairs and feed either exposed or in spinnings or internally in flowers, shoots, stems or seed heads of herbaceous plants. Some partially bite through a stem causing drooping of the shoot and then feed on the withered part. Pupae are usually also hairy and are often attached by a silken pad to a stem or leaf.
