The three endemic species of tussock butterflies are all restricted to the South Island. Their nearest relatives live in Australia.
This species (also known as tussock ringlet and Nelson tussock butterfly) is named after entomologist Anthony Clifford Harris, in recognition of his lifelong work on NZ insects.
It is restricted to montane grasslands of NW South Island, where it can share the habitat with any of the other tussock butterflies.

White to pale green at first, then mottled brown. Six days. Barrel-shapped with 15-18 vertical ribs.

Elongated, green, forked head. 12-18 days.

Overwintering has not been researched but is likely to be with half-grown caterpillars sheltering in the base of the tussocks.
