Species-level:

The wingspan is 1 - 1.4 cm. The forewings are brown with a distinct black band in the discal cell region.

Semioscopis inornata, the dull flatbody moth, is a species of moth of the family Depressariidae. It was described by Walsingham in 1882. It is found throughout Canada and northern United States. The length of the forewings is 10.5–15 mm. The forewings are bluish-gray. Adults are on wing from early April to the end of May in one generation per year. The larvae feed on Populus tremuloides, Populus grandidentata, Populus balsamifera and Salix species. They roll the leaves of their host plant.

The dawn flat-body is an intriguing species known for its nocturnal habits, displaying a remarkable ability to navigate the twilight by using its highly sensitive antennae. As a larval leaf miner, it burrows and feeds within the tissues of deciduous leaves, causing a distinct pattern of damage that is unique to its larval stage. This behavior is fundamental to its survival and development, and is a testament to the complex relationships between this creature and its habitat.

Ashinaga longimana is a moth of the family Oecophoridae. It is found in Taiwan. The wingspan is about 40 mm. The forewings are dark brown, with two broad, fuscous stripes running from the base to before the termen. The hindwings are somewhat paler than the forewings and the veins are darker. They have extraordinary long hind legs.

The wingspan is 7 - 12 mm.
