Monarch & Milkweeds
Few butterflies are more recognizable than the dramatic orange and black Monarch. This iconic butterfly is a favorite in backyards, but migrates from as far as Canada to a few overwintering sites in California and Mexico and back again. However, the butterfly has two weaknesses. First, the caterpillars of the Monarch can only eat one type of plant: milkweeds. If there are no milkweeds at its summer homes, there can be no Monarchs. The other weakness is that its long migratory path requires food along the whole route, otherwise adults will not survive migration.
Habitat loss all along the migration route is contributing to a decline of Monarchs. In 2022, the Monarch Butterfly was listed as endangered by the International Union for the Conservation of Nature. The U.S. Fish and Wildlife Service also recently determined that listing the Monarch under the US Endangered Species Act was warranted (but precluded by higher priority listings). By planting milkweed host plants and favorite nectar plants, we can support Monarchs along their migration routes and give them support as they face larger threats such as climate change and pesticide exposure.
By the way, mosquito sprays and other backyard pesticides are harmful to Monarchs, Monarch caterpillars, and other pollinators (according to many sources, but here is an article from Michigan State University). If you want to keep butterflies, stop the spray and plant native nectar plants and milkweeds. Our best plants for Monarchs are listed below.
