Monarch butterflies perform one of the world's most spectacular, annual, long-distance migrations. As autumn approaches millions leave the breeding grounds in the north and head south to wintering grounds - although it is subsequent generations that complete the return journey in the spring. The monarch's orange colour is a warning for predators to stay away, as the chemicals they get from feeding on milkweed plants makes the butterflies poisonous.
