What is

a butterfly?

Klyukhina Elena

Butterflies are insects that belong to the Lepidoptera order, which also includes moths. They are identified by their large, often colorful, and striking wings that have become synonymous with beauty. Adult butterflies generally live for weeks up to a year, and during that time some make mass migrations across long distances while others stay more local.

Hello! I’m a butterfly!

Can you tell me what is a butterfly?

Butterfly Life Cycle Stages

01

Egg! We will talk about this first.

Larva (caterpillars)! We will talk about this second.

Pupa! After that, we will talk about this.

Butterfly! Adult!

And we will talk about this last.

01

Look at the eggs on this leaf.

Many of these eggs will hatch.

Butterfly Life Cycle Stage 1. Egg! We will talk about this first.

Once female butterflies have found a mate and copulate, they lay their eggs on leaves , which are firmly attached via a glue-like substance that hardens quickly.

When an egg hatches, a tiny

caterpillar crawls out.

Did you know?

Egg size and shape vary between species but they are usually covered in a protective layer of wax, called chorion, to prevent exposure to the outside world. The eggs usually hatch within a few weeks unless it is laid in the wintertime, which will result in a resting phase and then the egg will hatch in spring.

Butterfly Life Cycle Stage 2 Larva (caterpillars)!

There are many kinds of caterpillars. Some are very colorful. Let me tell you more about caterpillars . A caterpillar's body is made up of 14 parts, including the head. The parts are called segments. SEG-MENTS. A caterpillar's head has eyes and a pair of feelers. It has a mouth and strong jaws for biting. too.

02

Larva (caterpillars)!

Below a caterpillar's mouth is a part called a spinneret.

SPIN-NER-ET. Something that looks like water comes out through the spinneret. It quickly hardens into a material that looks like string. The string helps the caterpillar stick to whatever it is crawling on. A caterpillar's body can be smooth. It can also be covered with hair. A caterpillar has lots of legs, too.

02

Butterfly Life Cycle Stage 2 Larva (caterpillars)! A caterpillar grows, but its skin does not . When a caterpillar gets too big, its skin splits. The skin splits near the caterpillar's head and down its back. The caterpillar crawls out of the old skin. Now it wears new skin. This happens over and over as the caterpillar grows. Finally the caterpillar grows as big as it will be. When this happens, it is ready for its next stage .

Butterfly Life Cycle Stage 3 Pupa! Here’s the most interesting stage in the butterfly life cycle – the stage for a complete change . Once fully grown, the caterpillar stops eating and becomes a pupa. The pupa, also known as a chrysalis, is a kind of a vessel within which the caterpillar transforms into a butterfly. You can also imagine it as a warm and cozy house.

Butterfly Life Cycle Stage 3 Pupa!

First, the caterpillar begins to look for a safe and isolated place to pupate. It can be under a tree branch, a twig, hidden in leaves, or it can also be buried underground. It then starts spinning a silk pad to cocoon itself. Cocoons can be hard or soft, translucent or opaque. And they come in a wide variety of colors, from yellow to green, brown, gold, or silver.

Butterfly Life Cycle Stage 3 Pupa!

From the outside, a pupa may not appear much. But there’s a lot happening on the inside.

The caterpillar’s body breaks down on a cellular level and becomes a nutrient-rich soup of sorts. It then begins to reconstruct itself. Slowly, butterfly wings, eyes, antennae, mouth parts, and other organs are formed. The metamorphosis consumes so much energy that the pupa loses nearly half of its weight.

Did you know?

Pupas are generally immobile!

But!

Some pupas have the ability to wiggle a little. They also make a hissing sound to frighten predators.

So it’s important for them to be camouflaged into the environment.

Butterfly Life Cycle Stage 4 Butterfly! Adult!

This stage is what most of us imagine when we think of butterflies. But there’s much that happens here that we may have not known earlier. By now, the caterpillar is finally done changing itself–from the antenna to abdomen. The result?

A colorful winged butterfly! If you’re lucky, you may even get to watch as the butterfly first emerges from the pupa.

Butterfly Life Cycle Stage 4 Butterfly!

The time it takes to break through the pupa varies from a few days to almost a year, depending on the species. This stage is also the stage for reproduction, as the butterfly is sexually mature. Good to know: Butterfly wings are actually transparent. They are covered with thousands of tiny scales. All they have to do is reflect light to make the different colors we see.

04

Butterfly Life Cycle Stage 4 Emerging Butterfly!

The pupa will split open but the butterfly will not take off just yet. Why? Because the butterfly’s wings are wet, soft, and crinkled. It will first hang with its wings down to dry them. It will also begin pumping a liquid into them so that they straighten out and become strong. It generally takes only 3 to 4 hours for an emerging butterfly to master the art of flying . Pretty impressive, right?

04

Butterfly Life Cycle Stage 4 Adult Butterfly!

Once fit for flight, the adult butterfly takes to the air in search of nectar to feed on. Most adult butterflies live for only 2 or 3 weeks. Only some species that hibernate during the winter live several months. The main job of an adult butterfly is to look for a mate. Flying comes in handy. They can travel distances and find the right host plant to lay eggs in.

And that’s the complete butterfly life cycle, ready once more to start all over again! https://www.youtube.com/watch?v=kVm5k99PnBk
