Monarch butterflies (Danaus plexippus) begin their annual fall migration in mid to late August. These butterflies are the great-great-grandchildren of the monarchs that migrated south last fall, overwintered in Mexico, and began one leg of the journey north.
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, cocoon, and adult).
• Report sightings of adults online at JourneyNorth.org . You can also view a map of the sightings so far this year.
