This species is endemic to New Zealand and has been found in both the North and the South Islands. As well as at the type locality, this species has also been collected at Mount Arthur at an altitude of approximately 1050 m, at Arthur's Pass, at Aoraki / Mount Cook, on the Milford Track, on the Clinton River and near the Homer tunnel.

Adults of this species are on the wing from December to February.
