The Viceroy is a famed mimic, resembling the distasteful Monarch; a useful ruse against hungry birds. Its wingspan of 6.3 - 7.6 cm is smaller than the Monarch but they have similar colouring and markings. The Viceroy has a thin, black line across the hind wing.

You might see the Viceroy in the Algonquin Highlands in moist, open areas such as lake edges and marshes, or even wood edges, roadsides and meadows, wherever Willows and Poplars grow. The female lays her oval eggs on the tips of host plant leaves. The caterpillar has an odd shape, olive or blotchy brown coloured with two spiny tubercles.

From May-September the adult butterflies can be found feeding on aphid honeydew, dung, and decaying fungi, and many flowers, such as Goldenrod and Canada Thistle.
