Diet
The viceroy caterpillar eats the leaves of willow and poplar trees.
Life Cycle
The viceroy mates in the afternoon. The female lays her eggs on the tips of the leaves of poplars and willows. There are usually two or three generations of viceroys born each breeding season.
Behavior
The viceroy and monarch were once thought to exhibit Batesian mimicry where a harmless species mimics a toxic species. Studies conducted in the early 1990s suggest that the viceroy and the monarch are actually examples of Mullerian mimicry where two equally toxic species mimic each other to the benefit of each. Just goes to show you there's always something new to discover in the natural world!
