Tingena lassa

Tingena lassa is a species of moth in the family Oecophoridae. It is endemic to New Zealand and has been observed in Otago. It frequents both subalpine habitat at altitudes up to 1100 meters down to sea level residential areas. This species' resting place on rock walls has frequently been spotted. Around November and December, you can see this species' adults flying.

Taxonomy
This species was first described by Alfred Philpott using a specimen collected by Charles Edwin Clarke at Leith in Dunedin in December and named Borkhausenia lassa. In 1939 George Hudson discussed and illustrated this species under the name B. lassa. In 1988 J. S. Dugdale placed this species in the genus Tingena. The male holotype specimen is held at the Auckland War Memorial Museum.
