Adult monarchs live for anywhere from 2 to 6 weeks, and females lay eggs and males mate throughout most of this period. They use a combination of visual and chemical cues to find milkweed. Females will wait a long time to find milkweed. Sometimes in our cages we keep mated females without milkweed, and VERY rarely, we will find a few eggs on other plants or the sponges we use to feed the females.
The caterpillars then die. We have done studies here at the University of Minnesota of females that were overwintering in Mexico. At no time between egg fertilization and death do all body parts break down. Many of the features unique to the adult—such as the wings, eyes, internal reproductive organs, and long antennae—are actually present as tiny clusters of cells even in the egg.
These cell clusters grow and differentiate throughout the larval stage. Some body parts, especially muscles, degenerate at the end of the larval stage and are replaced by new muscles that allow the new kinds of movements associated with the adult stage. Larvae move very differently than adults, and thus most of their muscles are completely broken down by enzymes early during the pupa stage. I try to video the whole cycle.
I notice that, during the first week of a chrysalid, it looks like it is empty, except at the top. This is why I have always wondered if the skin, itself, of the chrysalid, plays a significant role in the formation of the wings and other organs. I think this because of the immediate visible pattern of the wings, etc. It appears that the wings grow from the skin inward. A: The skin or exoskeleton of the chrysalis is shed, in a way similar to that in which the exoskeleton of each of the previous larval instars is shed.
While it may appear that the wings and other organs grow from the skin inward, they are actually present in the larva, and grow continuously in the last larval instar. During the wandering stage after the larva has stopped eating , the tracheal system that fills the wing veins develops, and as the larva pupates, the wing assumes the shape that it will have in the adult. This is a Greek word that means transformation or change in shape. Insects have two common types of metamorphosis. Grasshoppers, crickets, dragonflies, and cockroaches have incomplete metamorphosis.
The young called a nymph usually look like small adults but without the wings. Butterflies, moths, beetles, flies and bees have complete metamorphosis. The young called a larva instead of a nymph is very different from the adults.

It also usually eats different types of food. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult. Eggs are laid on plants by the adult female butterfly. These plants will then become the food for the hatching caterpillars.
Eggs can be laid from spring, summer or fall. This depends on the species of butterfly. Females lay a lot of eggs at once so that at least some of them survive. The next stage is the larva. This is also called a caterpillar if the insect is a butterfly or a moth.

The job of the caterpillar is to eat and eat and eat. As the caterpillar grows it splits its skin and sheds it about 4 or 5 times. Make a move! It was written on the wings of butterflies. You have to want to learn to fly so much that you Are willing to give up being a caterpillar.
Now I wonder: Am I a man who dreamt of being a butterfly, or am I a butterfly dreaming that I am a man? No butterfly ever remembers what it felt like being a caterpillar. It flies. The life cycle of a butterfly can teach us a lot about letting go of negative thoughts and feelings and finding a way to make progress.
