| Helastia salmoni | |
Helastia salmoni is a moth of the family Geometridae.[2] This species is endemic to New Zealand and is found only in Fiordland in the South Island. Adults of this species are on the wing in January and are nocturnal and attracted to light. Although similar in appearance to Helastia corcularia, H. salmoni can be distinguished as its forewings are a lighter white-grey. This species was named in honour of John Salmon.
Description
Craw described this species as follows:
Medium sized (r.f.l. 12.7-13.2 mm) triangular forewing. Upperside forewing whitish-grey with wavy brown transverse lines. Male antennae bipectinated.[3]
Craw went on to explain that this species can be distinguished from Helastia corcularia as H. salmoni has forewings the upper side of which is coloured white-grey whereas H. corcularia has a darker more slate grey colour.[3]
