These larvae then passes through the pupa stage to become a fully developed adult ladybug beginning the cycle again. The main parts of a ladybug are its head, red elytra, wings, abdomen, antenna, eyes, and legs.

After that, the larval stage begins which is a period of 21 days. Then the pupa stage begins, where they stick themselves to a leaf for seven days in the form of a pupa. Finally, an adult ladybug comes out of the pupa starting the cycle again.
