The
Monarch
is the best known and probably the most studied butterfly in the world. Adults
arrive in Ontario beginning in June and most migrate south in September.
A few butterflies continue to pass through Ontario into October. |

Eggs
are usually laid in the underside of milkweed leaves or sometimes on the
milkweed flowers. Generally there are only one or two eggs on a single
plant. The eggs among are the easiest butterfly eggs to find. |

The
familiar caterpillar
of the Monarch is poisonous to predators because of its diet of milkweed.
Mature larvae are quite safe from attack and they often make no effort
to hide on the food plant. |

Monarch
larvae often wander a considerable distance before pupating. For this
reason, the chrysalis
often found in unlikely locations. |
