Paradetis

Paradetis is a monotypic moth genus in the family Geometridae. Its only species, Paradetis porphyrias, also known as the orange and purple fern looper, is endemic to New Zealand. The genus and species were first described by Edward Meyrick, the genus in 1885 and the species in 1883. It is found in both the North and South Islands. This species frequents the ferny glens and the banks of mountain streams. It is thought to be widespread in native forests with high rainfall. The larvae likely feeds on the fern Hypolepis millefolium. Adults are commonly on the wing from December to February and fly by the day close to the ground. When at rest the adult has its fore-wings placed slightly backwards, the antennae extended forwards and the end of the abdomen turned upwards. Adults have been trapped via a Mercury-vapour lamp.
