Description
It is a medium-sized butterfly, with a variable wingspan of 48 to 50 mm in Tasmania, and 48 to 55 mm in New Zealand. The upperside of the forewings are dark brown to black toward the outer edges, with three small white patches and a wide, bright yellow bar, and dull red nearer the body. The rear wings are dull red with a black border, and a row of black circles with light blue centres near the edge.
The underwings are very different - the rear wing is various shades of brown with cryptic, irregular markings; the underside of the forewing has a blue eyespot on a black background that is highlighted by a yellow area above and below.
Distribution and habitat
Yellow admirals are relatively common throughout their range wherever their food plants occur. They prefer open country, wastelands and gardens where the stinging nettles, ''Urtica incisa

They grow to about 30 mm long before pupating. The pupa is about 20 mm long and is grey or brownish, with sharp bumps and has two white/silver spots on each side.

The flight period of the adult covers all the warmer months of the year and so varies with location, e.g. in Tasmania it is from November to May, while in Victoria it is from September to April.
