The adult Monarch Butterfly wing is orange, with ornate pattern of thin black lines and broad black margins on each wing. Black margins heavily spotted with white. Forewings narrow and triangular. Caterpillar heavily striped black, white and yellow.

Occurs in suitable areas throughout much of Australia, where it has been introduced. Mainly in the east and southeast (including eastern Tas), but also locally common in southwest WA, northern and southern NT, and north-western Qld.
What are its habitats & habits?
The Monarch Butterfly is found in a variety of wooded habitats, including gardens, where males typically establish and defend loose territories around larval food plants (mainly introduced milkweeds or dogbanes), waiting for potential female mates to pass through. Adults feed on nectar, and have slow, gliding flight.
