This is a medium-sized native NZ moth but a related species, N. amicus from Australia, is also found in NZ and the two interbreed here. N. amicus has a pair of long black hair-tufts containing barbed hairs arising on the thorax and which project in front of the head.
The caterpillars are referred to as 'woolly bears'. The magpie moth is one of several moths that is seen flying during the day in NZ.
