Ichneutica propria

Walker described this species as follows:

Pale fawn-colour. Thorax a little darker than the body elsewhere, with a very slight band of black dots. Fore wings with some slight black discal lines, with a deep black basal stripe, a little in front of which there is a black discal stripe shaded with brown; the exterior and marginal black dots as usual. Hind wings slightly cinereous, with paler ciliae. Length of the body 5 lines; of the wings 12 lines.The wingspan of the adult male of this species is between 31.5 and 39 mm and for the female is between 30 and 36 mm. It is possible that specimens of I. propria might be confused with faded I. atristriga, however the later species lacks the distinctive marking on the prothorax nor does it have the black mark running through the middle of the forewing.

I. propria is endemic to New Zealand. This species is only known from the Tongariro National Park and Pureora Forest in the North Island but is widespread in the South Island although it is more frequently found on the eastern side of that Island.

The adults of this species are on the wing from December to April but have been recorded in early to mid May. They are attracted to light. Adults of this species are known to pollinate Hoheria lyallii.

Although the larvae have yet to be described they have been reared on Poa cita and Festuca novae-zelandiae. The larvae also feed on introduced grass species. This adaption to feeding on introduced grass species seems to have ensured no decrease in population has taken place.
