Monarchs feed almost exclusively upon plants in the milkweed family, and toxic chemical compounds (cardiac glycosides) from the plants give the insect an unpleasant taste. The black and yellow stripes on the caterpillar and the striking black and orange colours of the adult serve as a warning to potential predators: "You don't want to eat me." Predators quickly learn to leave the Monarch alone. Another butterfly, the Viceroy, mimics the adult colours and pattern of the Monarch in an effort to fool predators into thinking it, too, tastes bad, even though it does not feed upon milkweed and therefore does not contain the bad-tasting compounds.

A Monarch butterfly does not want to conceal itself. It wants all potential predators to notice it and not mistake it for any other type of butterfly. The reason for this is that Monarch apparently taste terrible due to it's diet of milkweed when a caterpillar. Once a predator eats one it never wants to eat another. So the butterflies want to warn off the predators. Viceroy butterflies have noticed this and have adopted the Monarchs coloration. They are essentially saying to the predators "Hey! I look like a Monarch Butterfly so I probably taste bad. Leave me alone and go catch something tasty!"
The biggest threat to the monarch butterfly are wasps, bees, frogs, and especially people. Insects like to eat the eggs of Monarch Butterflies.
the monarch butterfly protects itself by its bright warning coloration. When a bird eats aMonarch butterfly, he will get sick and vomit it up. The next time, the bird will not eat a Monarch. The Viceroy butterfly also has similar coloration, but it does not produce the same somewhat poisonous chemicals that the Monarch does
