Hierodoris s-fractum

Hierodoris s-fractum is a moth of the family Oecophoridae. It is endemic to New Zealand and can be found only in the southern parts of the South Island. The male is larger than the female. This species is very similar in appearance to H. eletrica however H. s-fractum has an interrupted silver S-mark on the forewing and longer labial palps. The larvae has not yet been described. Hoare hypothesised that the larvae of this species likely feeds on leaf-litter. The species seems to prefer open dry areas and can be found in native shrub and gorse.
