The butterfly is an insect. Butterflies are noted for their wings, which
are often colorful and bright.
Butterfly wings are a bit like bird wings. Bird wings are made of
feathers, but butterfly wings are made of tiny overlapping scales.
The wings are colored in various patterns. Some butterfly wings
are colourful. The colour comes when light hits the scales.
Butterflies have an interesting life cycle. They start as eggs. When
they are born, they are what we call caterpillars. This is the larval
stage for the caterpillar. The caterpillars then move into a cocoon,
becoming what we call a chrysalis. This is the pupal stage. When
the insect comes out of the cocoon, we call it a butterfly. This is the
adult stage for the butterfly. These clear stages of changing on the
way to adulthood are called metamorphosis.
Butterflies can be found almost all over the world. There may be as
many as twenty thousand different species of butterflies.
Butterflies usually eat flower nectar. Because of this, they are
important to the life cycle of many flowers. Butterflies also need
minerals, which they usually get from water found in dirt and sand.
