The
Viceroy
flies in Ontario from late May to early October. There are two extended
broods with the larvae over wintering. Any marshy area with Willows or Poplars
will usually have a population of Viceroys. |
 |
Eggs
are laid on the extreme tip of the food plant leaf and are relatively easy
to locate. Fewer eggs are laid in the spring and early summer than
in the late summer and fall. |
 |
The
larvae
are most conspicuous in April and May before the leaves have opened fully.
During this time it is common to find a group of four or more caterpillars
feeding on the same plant after emerging from hibernation.

Viceroy
chrysalises
are often made on the food plant but they are more difficult to see than
the larvae or eggs. The Viceroy resembles the much larger Monarch in
colouration. Recently, it also has been found to be poisonous to predators. |
