Butterfly Life Cycle

Butterflies are considered to be the prettiest insects and belong to the order Lepidoptera. Lepidoptera is a greek term that defines “scaly wings” of an insect which is true in the case of butterflies. These scaly patterns that are placed on the wings of butterflies in colorful designs, gives every butterfly a distinctive look.

Although butterflies fall under the order Lepidoptera, butterflies primarily fall under the super family known as Papilionoidea. Under Papilionoidea insects such as butterflies except moths Hedyloidea.

Butterfly Metamorphosis:

Metamorphosis in butterflies is complete metamorphosis because of its distinctive stages: the egg, the larvae (Caterpillar), the pupa (Chrysalis) and the adult stage. The insect’s physical features are different in all the stages of metamorphosis.

Life Cycle of a Butterfly:

Sometimes an adult butterfly is called imago. The adult butterfly has compound eyes, two antennas and dust-like scales on the wings and legs that come off if one came in touch with the insect.

1) The Egg – Stage 1:

The female butterfly lays the egg on the surface of a leaf or a stem. The egg is tiny, oval or cylindrical and varies in color. The popular larvae form of a butterfly known as the caterpillar gradually grows inside the egg. These eggs hatch according to the favorable conditions outside, if it’s warm the eggs faster otherwise it takes a few weeks.

2) The Larva (Caterpillar) – Stage 2:

The larvae or in this case a caterpillar that hatches goes on an eating rampage. In this stage they eat, molt and repeat that process constantly. After hatching the caterpillar is extremely hungry and eats constantly. The caterpillar eats it way out of the egg and then continues to eat plants in the outside world.

3) The Pupa (Chrysalis) – Stage 3:

The caterpillar forms a vessel around it, called the ‘pupa’. Inside the pupa the caterpillar gradually grows and develops. During this stage the pupa creates skins around the vessel that makes the exterior hard. The chrysalis protects the pupa till it transforms into a butterfly and breaks out of the vessel.

4) The Adult – Stage 4:

The most prominent and known stage to human beings is the adult stage when the Chrysalis breaks out of the vessel with colorful scaly wings. At first these scaly wings are folded against the body of the butterfly because of its brittle nature. Once it pumps blood into the wing the butterfly flies in search of food and other butterflies to mate with. After the mating is completed, the female butterfly lays eggs on a leaf or flat surface and the whole cycle begins all over again.

Conclusion:

Butterflies are cold blooded insects that require external temperatures to create body temperature. In extreme cold temperatures, the butterfly spreads its wings on a leaf, pile of mud or rocks to acquire sufficient body heat.
