Females do not have the small black spot.

Monarch butterflies are an iconic species, easily recognized by their large and vibrant orange wings. Monarchs carry out one of the most incredible cross-continental journeys in the animal kingdom, traveling upwards of 3000 miles from Canada and the northern United States to the forests in the mountains of Mexico.
