Monarch butterflies (Danaus plexippus) begin their annual fall migration around mid-August. These butterflies are the great-great-grandchildren of the monarchs that migrated to Mexico last fall. You can help monarchs by providing food (nectar) and keeping those areas protected:
- Turn a portion of your lawn into a wildflower meadow—plant milkweed or other native wildflowers.
- Delay mowing areas with milkweed until later in the fall.
- Avoid using herbicides—they kill all life-stages of monarchs (egg, caterpillar, pupa, and adult).
- Report sightings of adults online. View a map of the sightings so far this year.
