Metamorphosis from Caterpillar to Butterfly

The word metamorphosis comes from the Latin words for changing shape and in this movie you will get the opportunity to see three  stages in the life cycle of the the butterfly. First the caterpillar, next the chrysalis and finally a beautiful butterfly emerges.




















These are the caterpillar of the Cabbage White butterfly. They are great eating machines and have been living on the underside of the cabbage leaves in our school garden.
The larger ones look ready to pupate but you will have to read Katie's post to find out their fate.

The Peacock butterfly lays her eggs on the underside of a stinging nettle.When the caterpillars emerge they are highly conspicuous. In order to protect themselves from predators they cover themselves in a type of web.  If you look carefully at this picture you will see tiny caterpillars feeding inside a type of web. When they have eaten all the nettle inside the web they move on to another part of the nettle.

















These caterpillars are much larger, are jet black in colour and their bodies are covered in tiny spikes. They moult several times as they outgrow their skins. On the right of the picture you can see the remains of their protective web.























Bull Island is about one kilometre as the crow flies from our school. I was fascinated to find that a butterfly conservationist counted 298 Marsh Fritillary butterflies there one morning last June.
