Eudonia asterisca is a moth in the family Crambidae.[3] It was named by Edward Meyrick in 1884 and is endemic to New Zealand. It has been recorded in both the North and South Islands. This species is recorded as being present at sea level up to altitudes of 1350 m. This species has been recorded as inhabiting native podocarp/hardwood forests. The adults of this species are on the wing from December until March although they have also been recorded in October and November. They are attracted to light and have also been trapped via sugar traps.

Taxonomy

This species was first described by Edward Myrick in 1884 using specimens collected at Arthur's Pass, Mount Hutt, Lake Wakatipu in January and named Xeroscopa asterisca.[4][5] Meyrick added further described the species in 1885.[5] In 1913 Meyrick placed the species within the genus Scoparia.[6] George Hudson described and illustrated this species in the book The butterflies and moths of New Zealand.[7] In 1988 John S. Dugdale placed this species in the genus Eudonia.[2] The male lectotype, collected at Lake Wakatipu by R. W. Fereday, is held at the Natural History Museum, London.[2]
