The Life Cycle of a Butterfly
By Mary | March 7, 2010
Thanks to its fascinating life cycle butterflies have always represented the transformative energy of life, but do you know the exact stages of a butterfly’s life cycle? And do you know that each stage of that cycle serves an important purpose in the butterfly’s development – just like the different stages in human development?
There are four stages in a butterfly’s life cycle.
The first stage is when the insect is just a tiny egg. Butterfly eggs vary in shape and size depending on the type of butterfly – they can be round, oval or cylindrical. You will usually find butterfly eggs on plant leaves or stems, usually on a plant that the butterfly knows will be food for its future offspring. Nothing much happens during the egg stage – nothing visible anyway – but just like human babies in the womb inside the egg a tiny caterpillar is growing.
The second stage is the caterpillar or larva stage – the egg hatches to reveal a small worm-like caterpillar. At this stage the future butterfly looks nothing like a butterfly – in fact, if humans hadn’t observed these different stages no one would even guess that a caterpillar had anything to do with a butterfly! Whilst caterpillars can cover quite some distance on the ground, from plant to plant, on the whole they stay close to where they were hatched. The caterpillar’s job is to eat and grow, and learn about its surroundings. During this stage, as it eats and grows, the caterpillar sheds its skin several times to make room for all these growth spurts. Just like human children, caterpillars grow at an alarming rate!
The third stage is the chrysalis or pupa stage. Once the caterpillar has grown to its optimum size, it locates a comfortable place to rest and cocoons itself entirely in a skin-like silk cover. Inside this cover a miraculous transformation takes place – the caterpillar tissue disintegrates and the butterfly’s body and wings grow. This stage is a bit like how teenagers often retreat to their rooms for a few years, experiment with different attitudes, clothes and hairstyles, and then eventually come out again as young fairly well formed adults! The difference is that for butterflies this stage only takes a few weeks!
The final stage is the adult or imago stage, when the beautiful butterfly emerges from the chrysalis. The butterfly is now ready to really explore the world, takes flight on its fresh wings and goes off in search of a mate and possibly a new place to live. In time the butterfly will also lay new eggs and so the cycle starts again. In the same way, human adults seem programmed to spend some time learning and growing before they are ready to explore their environment and be free to make their own way in the world.
