- Te Ao Māori
- Argyrophenga antipodum has no recognised Māori name. It lives in the tussock grasslands. This is a landscape of significance to Māori for hunting and travel. The butterfly is part of that landscape.
Grassland species. Subtle browns, not flashy but very "NZ landscape". Argyrophenga antipodum, the Common Tussock, is a butterfly of the grasslands. It flies low among the tussocks. A soft brown against the green and gold. The wings are brown above, with a small white spot. The underside is patterned with brown and grey.
The wingspan is small. About three centimetres. The caterpillars feed on native tussock grasses (Chionochloa species). The pupa is brown. It is hidden at the base of a tussock.
The Common Tussock lives in native grasslands, tussocklands, and open areas. It likes the high country. It likes the windswept plains. It is a butterfly of the landscape.
The species is endemic to New Zealand. It is found only in the South Island.
The name Argyrophenga means silver-winged. Antipodum means of the antipodes. The butterfly is named for its home.
The Common Tussock is not threatened. Its habitat is extensive. But tussock grasslands are threatened by farming and fire.
This butterfly is a reminder. Not all butterflies are flashy. Some are subtle. Brown on brown. They are no less beautiful for being understated.
