BUTTERFLIES are insects. There are over 20,000 different species around the world. They are often called flying flowers because of their bright and pretty colours.

2 BUTTERFLIES are insects. There are over 20,000 different species around the world. They are often called flying flowers because of their bright and pretty colours. During their short life they go through an amazing transformation. They begin as an egg, then go from a caterpillar into a chrysalis, before finishing as a butterfly.

3 A female butterfly will lay eggs only once in her life. Some species lay them one at a time, some in small groups and some in their hundreds. Butterflies lay eggs on plants that their caterpillar likes to eat.

4 Once the egg hatches, a caterpillar spends most of its time looking for food. Some caterpillars can eat 27,000 times their own weight in just a few weeks.

5 When a caterpillar is fully grown it looks for somewhere safe to pupate usually on the underside of a leaf or branch. The caterpillar attaches to the surface with a small silk pad. It then sheds its skin to reveal a chrysalis underneath.

6 Inside the chrysalis the cells of the caterpillar are broken down and rebuilt as a butterfly. This transformation takes about two weeks. For some species it can take several months.

7 Butterfly wings are covered in tiny scales, similar to those of a fish. When a butterfly emerges from the chrysalis, its wings do not work. They have to wait for them to fill with blood before they can fly. Glasswinged Butterflies have see-through wings, as they are not completely covered in scales.

8 A butterfly has a long, hollow tongue known as a proboscis. When it isn t being used, it looks like a curly straw. They use their proboscis to feed on nectar, a liquid produced by flowers that is rich in sugar.

9 They can drink liquids from other foods, such as tree sap, dung and rotting fruit. Butterflies also get other nutrients by drinking from muddy puddles.

to find their way. Butterflies have compound eyes.

10 On top of a butterfly s head are the antennas. These help butterflies to smell, keep their balance while flying and also to find their way. Butterflies have compound eyes. These are made from thousands of individual parts, making them very good at sensing movement. This helps them avoid predators.

11 Butterflies are preyed on by many different predators, including mantises, wasps, spiders and birds. Some butterflies survive by blending into their surroundings. Others have markings that look like eyes, which can frighten predators away.

12 If a butterfly survives long enough it will try to mate. The female begins the process by releasing pheromones, which attract a male to her. Males can detect pheromones from over a kilometre away. Butterflies mate by touching their abdomens together. The male releases sperm, which fertilises the female s eggs.
