Monarch butterflies utilize different habitat in the warm months versus the cold months. In the spring, summer and early fall, they can be found wherever there are milkweeds. Monarchs lay their eggs on milkweeds and they're always searching for them in fields, meadows and parks.
Gardening for Butterflies. Because butterflies are attracted to flowers, it is easy to plant a garden that both you and they can enjoy. Some of the species you may attract are listed in the table at right. A butterfly-friendly garden contains both adult nectar plants and caterpillar host plants. A few common vegetables also serve as caterpillar host plants. Many butterfly gardeners plant extra vegetables, enough for them and their caterpillars. As an added bonus, butterfly gardens often attract hummingbirds.
