Synemon
Synemon (commonly known as the Sun-moths) is a genus of moths within the family Castniidae. It was described by Edward Doubleday in 1846. The genus contains 24 described and 20 undescribed species. These species are found across mainland Australia and on Kangaroo Island, with the highest diversity in Western Australia. Synemon species can be found in a range of habitats, including woodlands, heathlands and native perennial grasslands. The adults fly during the daytime in warm to hot weather. They have clubbed antennae, and are often mistaken for butterflies. Sun-moths typically have dull coloured forewings which, at rest, conceal their brightly coloured hindwings. The hindwings can be used to startle potential predators. All known larvae of sun-moths feed on monocotyledonous plants, such as Rytidosperma, Gahnia, Lepidosperma and Lomandra. Since European settlement, many species have suffered drastic reductions in their distributions due to habitat loss from agriculture and other threats. Some are listed as threatened, including Synemon plana, which is listed as critically endangered under the Australian Government Environment Protection and Biodiversity Conservation Act 1999. Species
