Dichromodes cynica (also known as the rock face moth)[1] is a moth of the family Geometridae.[2] It was first described by Edward Meyrick in 1911. D. cynica is endemic to New Zealand and is found only around Christchurch and Banks Peninsular. The larvae of D. cynica are cryptic in appearance and feed on lichens growing on dry sunny rock faces. Adults are on the wing from September to February. D. cynica are active during the day and are rapid fliers.
This species was first described by Edward Meyrick in 1911 using a specimen collected by George Hudson at Lyttelton in November.[3] George Hudson discussed and illustrated this species in his 1928 book The butterflies and moths of New Zealand.[4] The male holotype is held at the Natural History Museum, London.[5]
The larvae of this species are cryptic, camouflaging themselves against their host species of lichens.[6] [7]
Hudson described the larvae as follows:
