Hydriomena purpurifera
Hydriomena purpurifera is a species of moth in the family Geometridae. It was first described by Richard William Fereday in 1883. This species is endemic to New Zealand. The classification of New Zealand endemic moths within the genus Hydriomena is regarded as unsatisfactory and in need of revision. As such this species is currently also known as Hydriomena (s.l.) purpurifera. References
