Question 1

Practice Question:

Define the term metamorphosis. Briefly describe the various stages occuring in the life cycle of a butterfly.

Solution:

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

Life cycle of butterfly:

There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult.

Egg: 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.

Caterpillar: The Feeding Stage. 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. Food eaten at this time is stored and used later as an adult.

Adult: The Reproductive Stage. The adult stage is what most people think of when they think of butterflies. They look very different from the larva. The caterpillar has a few tiny eyes, stubby legs and very short antennae. The adults have long legs, long antennae, and compound eyes. They can also fly by using their large and colorful wings. The one thing they can't do is grow.
