Postman butterfly

Its caterpillars take the poison from passion flower leaves and keep it in their bodies to protect themselves.

It looks almost the same as another butterfly, the red postman. Both are poisonous, so birds learn one lesson for two butterflies.

It can see ultraviolet light, which helps it spot tiny differences in other butterflies' wings.

Pollen sticks to its long tongue as it feeds, so it helps flowers make seeds.

In different places it has different wing patterns, so scientists love to study it.
