Getting there is half the fun. In one of the most spectacular natural phenomenon of the insect world, adults make mass migrations from August — October, flying to hibernate along the California coast and in central Mexico. At the wintering sites in Mexico, they roost in trees and form huge aggregations that may have millions of individuals. They leave for the north in the spring. What really makes this amazing is that the butterflies making this pilgrimage have never done it before! How?s that for Mother Nature and instinct?

Found in fields, meadows, prairie remnants, urban and suburban parks, gardens, and roadsides. Overwinter in conifer groves.
Caterpillars eat plants in the milkweed family. Hence the name. Adults take nectar from a variety of flowers.
In migration, females lay eggs along the way on the leaves of the milkweeds. Caterpillars eat the leaves and flowers. The migration south and then northward return spans the life of three to four generations of the butterfly.
