Egg (Butterfly Stage)

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 colour. The popular larvae form of a butterfly known as the caterpillar gradually grows inside the egg. These eggs hatch according to the favourable conditions outside, if it’s warm the eggs faster otherwise it takes a few weeks.

Larva (Butterfly Stage)

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

Pupa (Butterfly Stage)

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.

Adult (Butterfly Stage)

The most prominent stage known to human beings is the adult stage when the Chrysalis breaks out of the vessel with colourful 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.

The Butterfly Life Cycle

The butterfly and moth develop through a process called metamorphosis. 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.

Monarch butterfly

The monarch butterfly or simply monarch  (Danaus plexippus) is a milkweed butterfly  (subfamily Danainae) in the family Nymphalidae.[6] Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown.[7] It is among the most familiar of North American butterflies and an iconic pollinator,[8] although it is not an especially effective pollinator of milkweeds.[9] Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 cm (3.5–4.0 in).[10] A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing.

Swallowtail butterfly

Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus Ornithoptera.[1]

Sea Butterfly (Thecosomata)

Sea butterflies aren't typical marine gastropods. These free-floating creatures have evolved unique physical features over time. 

Often delicate and transparent, their shells are mostly non-existent or greatly diminished in some families. Their snail foot has evolved significantly into wing-like lobes that help them navigate the ocean’s currents.

Its shells are made of calcium with varying shapes, from needle-like to globular. These structures measure less than half an inch, invisible to the naked eye.

Recognized as one of the most populous gastropod species, Sea Butterflies play a crucial role in the oceanic food chain and carbon cycle. Their size masks their immense ecological influence4 beneath our oceans' surface.

Caterpillars are not separate species, but they are larvae of butterflies and moths

Are caterpillars insects? The answer is yes, but they are an incomplete form of certain insects4. Caterpillars are the larval stage of 180,000 insects belonging to the order Lepidoptera, which includes butterflies and moths. Caterpillars develop to become their winged adult form.

Generally, caterpillars have a cylindrical body shape with a segmented structure. Each body segment typically bears a pair of legs. 

They live on every continent except Antarctica. Some countries known for their diverse caterpillar populations include the United States, Brazil, Australia, India, China, and African and European countries.
