Monarch butterflies

Description:

The monarch butterfly is reddish-orange with black vein-like markings. There is a black border around its wings with white spots on it. Its wings look like stained glass windows! When its wings are open, they are about four inches wide. Males and females are similar in appearance, but the the black veins are thicker on the female's wings and the male has small pouches on their hind wings where they store pheromones. The bright orange of the monarch is a type of advertising coloration that warns predators away

Habitat:

In the spring and summer, the monarch butterfly's habitat is open fields and meadows with milkweed. In winter it can be found on the coast of southern California and at high altitudes in central Mexico.(but why are there also in Indonesia?)
