Austrocidaria arenosa is a species of moth in the family Geometridae. It is endemic to New Zealand. This moth is classified as "At Risk, Declining" by the Department of Conservation.

Taxonomy[edit]

This species was first described by George Howes in 1911 using specimens collected at Mr O'Connors house at Titahi Bay, Porirua and given the name Eucymatoge arenosus.[3] George Vernon Hudson discussed and illustrated this species in his 1928 publication.[4] Hudson changed its epithet to arenosa.[4] In 1988 John S. Dugdale discussed this change and assigned the species to a new genus Austrocidaria.[2] The holotype specimen is held at the Natural History Museum, London.[2]

Description[edit]

Howes described the adult moths of the species as follows:

Male and female, 26 lines. Head and thorax whitish-ochre, slightly touched with grey. Abdomen whitish-ochre with black bar interrupted in centre on apex of all segments. All wings whitish-ochreous, crossed by waved darker striae. A slight darker suffusion from apex towards centre of forewing. Cilia greyish-white, with a darker-grey line at base. A series of minute black marks along veins and around termen.[3]

Distribution[edit]

This species is endemic to New Zealand.[1][5] As well as the type locality of Titahi Bay, A. arenosa has also been recorded as occurring at Moeraki near Oamaru,[4] at Paekākāriki,[6] and near Cass.[7]

Biology and life cycle[edit]

This species is attracted to blossoms, sugar and light.[3] Adult moths are on the wing between November and March.[3]

Conservation status[edit]

This moth is classified under the New Zealand Threat Classification system as being "At Risk, Declining".[8]
