Monarchs migrate farther than any other butterflies in the world– up to 3,000 miles and back. Milkweed is an important food source, especially for monarch caterpillars. Many other native wildflowers also provide nectar for adults along their migration route. In this Botany Hall diorama of Presque Isle, a monarch visits the flowers of the hairy puccoon (Lithospermum caroliniense). Presque Isle is the only known existing site in Pennsylvania with this plant species.
