Friend or Enemy?
Voice 1
Welcome to Spotlight. I’m Adam Navis.
Voice 2
And I’m Liz Waid. Spotlight uses a special English method of broadcasting. It is easier for people to understand, no matter where in the world they live.
Voice 1
Human life is full of friends and enemies. And in a strange way, this is also true in all of nature! Big and small creatures learn their friends very quickly. In nature, this is called a symbiotic relationship. In these relationships, both creatures help each other. Today’s Spotlight is on some of these symbiotic relationships.
Voice 2
A beautiful winged insect moves through the air. It stops on the leaves of a nearby tree. If you look closely, you can see its wings open and close. This permits you to see the beautiful fine details, and bright fire colours. It is the monarch butterfly. It is so small and light! So how does such a creature defend itself? It does not seem to have any defences - no poisonous bite, or a painful sting. So what does it do?
Voice 1
Well, nature usually provides some kind of weapon. And, naturally, this is also true for the monarch butterfly. But the monarch’s secret weapon lies in its body. And it begins right at the start of the monarch’s life - as an egg. Adult monarchs stick their eggs under leaves. The leaves are always those of the milkweed plant. This plant is central to the monarch’s defence system.
Voice 2
Like all butterflies, monarchs begin life as caterpillars. The long, soft caterpillar breaks out of the egg. It does not yet have wings. Immediately, it finds food. It eats the milkweed leaves. The caterpillar fills itself with the milky substance contained in the leaves. And it grows very quickly. When it is about five centimetres long, it stops eating. A kind of shell develops around the caterpillar - a chrysalis. The caterpillar develops inside the green and gold chrysalis. In about two weeks, it changes into a beautiful monarch butterfly.
Voice 1
The butterfly is still full of the milky substance from the milkweed leaves. And this substance contains a poison. It does not harm the butterfly. But it does make it taste bad to birds and animals. Creatures that eat this butterfly become sick. They do not die. But they do remember that this brightly-coloured insect made them sick. They soon learn to avoid all monarch butterflies. The milkweed plant helps this butterfly to defend itself from harm. The plant is a true friend to the butterfly!
Voice 2
This is how nature works. It is like having friends and enemies. And each creature and plant knows which is which! All caterpillars have many enemies. They are small, soft creatures. And they are easy to attack. Birds and other animals like to eat caterpillars. And flying insects like wasps like to lay their eggs on caterpillars! But just like the monarch caterpillars have milkweed plants, other kinds of caterpillars have other friends. For the lycaenid caterpillar, this is another insect, the ant. The ant can guard the caterpillar. The ant releases a particular liquid. This liquid smells bad to attackers - so they stay away. In return for this service, the caterpillar produces a sweet liquid for the ant to feed on. What are friends for?
