Teacher support materials The Wanderer Butterfly's life cycle, like all moths and butterflies, involves undergoing metamorphosis. Show The female butterfly lays an egg and the larva or caterpillar hatches out of the egg within two to three days. The newly hatched caterpillar eats its own egg and then eats leaves to get energy to grow. The caterpillar grows and moults many times, and after about three to four weeks it begins to pupate. To do this, the caterpillar attaches itself to a branch with a button of silk, hangs upside down and its chrysalis forms after its final moult of caterpillar skin. After ten days of pupation inside the chrysalis it emerges as an adult butterfly. As an adult, it drinks nectar from flowers using its long tube-like tongue called a proboscis. From the nectar it gets energy to fly, reproduce and lay eggs for another generation. The image gallery below shows the Wanderer Butterfly growing and changing as it starts life inside an egg, hatches out as a caterpillar, and finally metamorphosises into a butterfly.

ExplainLiving things grow, change and have offspring similar to themselves. But in the case of a butterfly the young look very different to the adults. As caterpillars, they crawl, eat and grow. They are not able to reproduce or move great distances. As butterflies, they drink nectar, move by flying and can reproduce. Since the young eat and live differently to the adults they are not competing for the same food or places to live. Elaborate
Evaluate students' understanding
How old is a caterpillar when it turns into a butterfly?Many species will spend less than a week undergoing metamorphosis, but most will emerge as a butterfly within about three weeks.
What is the life cycle of a caterpillar?They develop through four life stages: the egg, the caterpillar or the larva, the pupa (chrysalis in butterflies), and the adult (moth or butterfly).
How long does it take for butterflies to go from caterpillar to butterfly?It will take approximately 4 weeks to transform from larvae to butterfly.
How long does it take for a caterpillar to evolve?Reproductive organs will form (they were absent in the larval stage). And all of this happens in just 10 - 14 days. In just 9 to 14 days the transformation from caterpillar to butterfly is complete.
