Wilson, Biologist, The ephemeral beauty of the butterfly and the peculiarity of its life cycle symbolize transformation in nature and the passage of time. A larvas main job is to grow and molt, a process triggered by hormones. In insects that undergo incomplete metamorphosis, the larvae are called nymphs. Once the larva embeds a hook-like structure at its rear end into the button, the rest of the skin can slip off.

Once fit for its first flight, the butterfly takes off in search of 1. Help them explore the relationship between very large creatures such as baleen whales and extremely small ones such as the krill they feed upon. Fourth Stage: Adult.

The butterfly and moth develop through a process called metamorphosis. Parents and offspring arent competing for resources, allowing both life stages to develop independently. Stage 1: Egg Many butterfly species depend on a single species of plant for food, while most plants rely on butterflies and other insects for pollination. Heres why each season begins twice. We empower you to efficiently solve each new challenge and make your life better and easier. Adult monarchs live for about two to six weeks in the summer months, but the generation that travels to Mexico lives through the winter, for a total of up to nine months. Female monarchs will generally lay one to as many as three eggs on the underside of milkweed leaves. Food eaten at this time is stored and used later as an adult. Old cells hang around as we age, doing damage to the body. Large compound eyes allow 180 degrees of vision. Once complete, theyll hang upside down from a perch on a silken thread. Dry conditions will hinder the hatching of the eggs and the development of the milkweed, the only plant that the monarch caterpillar eats, and can reduce flower nectar that the adults eat. At this stage, it sheds its skin four or five times. % This is a Greek word that means transformation or change in shape.
