The monarch butterfly is orange in color with black veins throughout their wings; there is also a large black border with white dots in 2 rows. They have a wing span of 10 cm. The monarch caterpillar (the stage before it spins its cocoon and becomes a butterfly) is striped yellow, black and white. The butterflies live on a plant called milkweed and live in areas where there are flowers surrounding them. The monarchs fly down to Mexico for the winter but this trip is hard and many of their babies do not make it back.
Why is the Monarch Butterfly considered a special concern group?
The monarch butterflies are not yet endangered but with a decrease in the milk weed plant and a decrease in the land where they migrate to in the winter; it is harder for the butterflies to survive because they have less area to live on and not as much food to eat.
