This species is endemic to New Zealand. It is restricted to the North Island and can be found south from Taupō in scattered locations. Other than the type locality of Wellington it has also been found Taranaki, Hawkes Bay, Rangitikei and Wairarapa. Only the grey form of this species has been found in Wellington and very few specimens have been collected outside of this locality. Specimens obtained in Taranaki and Rangitikei have been of the black and white form but examination of the genitalia has shown they are of the same species.

The larvae and biology of this species is unknown as at 2010. Adults of this species have been recorded in December and January. Hudson states that the species has been seen in November and adults could be found resting on fences in Wellington city.
