About
The famous Monarch-mimic, the Viceroy, is often listed as the classic example of Batesian mimicry. The harmless Viceroy has evolved to closely resemble the Monarch, whose diet of milkweed makes it toxic to predators. After a wicked Monarch hangover, most predators elect to steer clear of the orange ones, and the harmless Viceroy shares the advantage.
