Butterflies have the typical four-stage insect life cycle. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis.

Every species of butterfly on a board is labeled with a number. That number can be typed into a computer screen in front of the hatcheries and information about that species will pop up. Once all the work is done, it is a game of sit-and-wait. It takes about 2 weeks for all the butterflies to emerge from one board.

As the boy tried to figure out what had gone wrong his mother took him to talk to a scientist from a local college. He learned that the butterfly was SUPPOSED to struggle. In fact, the butterflys struggle to push its way through the tiny opening of the cocoon pushes the fluid out of its body and into its wings.

Monarch butterflies go through four stages during one life cycle, and through four generations in one year. Its a little confusing but keep reading and you will understand. The four stages of the monarch butterfly life cycle are the egg, the larvae (caterpillar), the pupa (chrysalis), and the adult butterfly. The four generations are actually four different butterflies going through these four stages during one year until it is time to start over again with stage one and generation one. In February and March, the final generation of hibernating monarch butterflies comes out of hibernation to find a mate.

Larvae of a few butterflies (e.g., harvesters) eat harmful insects, and a few are predators of ants, while others live as mutualists in association with ants. Culturally, butterflies are a popular motif in the visual and literary arts.

The little boy was thrilled to hear about the changes his caterpillar would go through. He watched every day, waiting for the butterfly to emerge. One day it happened, a small hole appeared in the cocoon and the butterfly started to struggle to come out. At first the boy was excited, but soon he became concerned.

Thanks for sharing the behind the scenes story of the Butterfly Center. It is funny to think of shipment of butterflies winging their way around the world. Thanks alot for sharing! It was very interesting to know how and where these butterflies get shipped 🙂 It sure is a long process. I was very excited to read about the behind-the-scenes for the CBC.

Butterfly Life Cycle / Butterfly Metamorphosis. Lets explore a butterflys life cycle in detail, including all four stages of life. To grow into an adult they go through 4 stages: egg, larva, pupa and adult. Each stage has a different goal - for instance, caterpillars need to eat a lot, and adults need to reproduce.
