News: Over 1,200 Miles

The final monarchs from Mexico are officially on their way! With the northernmost now in Oklahoma, the butterflies have spread a distance of 1,200 miles.

Just think...The population that occupied only 1.65 acres of winter habitat has now expanded into over 200 million acres of breeding habitat.

Following Milkweed
Monarch migration evolved in response to seasonally-available milkweed. As the growing season in the north begins, monarchs follow this vital resource. Watch the milkweed map to see how closely the migration is tied to milkweed growth.

How Many Eggs?
Monarchs have tremendous reproductive potential. The egg chart shows how many eggs one monarch can lay. As you study the migration map, think about the eggs monarchs have laid across the landscape.
