Classification

| Subfamily: | Archiearinae |
| Genus: | Archiearis |
| Species: | notha |
| Authority: | (Hübner, [1803]) |
Nationally scarce (Nb) in ancient woodland and open woodland in parts of southern England. In Hampshire and on the Isle of Wight seems to be present wherever Aspen is established, however in places such as Crab Wood, some of the few trees have been felled to the detriment of this and other local species. Wingspan 33-36 mm. The most likely confusion species is Orange Underwing A. parthenias, which see for differences. Larva feeds on Aspen, over-wintering as a pupa.
