In science, we have been learning about life cycles. Here are some explanation texts about the life cycle of a butterfly.
The Life Cycle of a Butterfly
The wonderful life cycle of a butterfly
All butterflies have four stages in their life cycle. Each and every one of these stages also have goals. A caterpillar turning into a butterfly is the main stage. Also, a butterfly becoming an adult is called metamorphosis. Metamorphosis is where something undergoes a change because it doesn’t look like the adult, or is different to the adult.
STAGE 1: EXTRAORDINARY EGGS:
The eggs are laid by the female, just like any egg-laying creature, with the exception of sea-horses. They are about the size of sesame seeds and are usually found on the underside of leaves or twig. They are laid close together and in mounds of hundreds.
STAGE 2: LOVELY LARVE:
Stage 2 is the caterpillar hatching and emerging from its egg. It starts by chewing a hole in the side of the egg. Soon enough it emerges at only two millimetres long, small enough to sit on the head of a pin. Whilst they are young, caterpillars are virtual eating machines. They feed, all the time, on milkweed leaves. This helps them grow. After they have spent five days in their egg, they emerge only to eat, grow and become butterflies. Whilst they are rapidly growing, they are also rapidly shedding skin.
STAGE 3: PERFECT PUPA:
Stage 3 is the caterpillar shedding its final skin. It sheds its skin and becomes a pupa. This is called ‘pupation’. Once it becomes a pupa, it remains immobile for one and a half weeks, its leaf like appearance camouflaging it.
STAGE 4: FIRST FLIGHT:
Once the larva has finally emerged-finally as a butterfly-it will stick to the chrysalis (pupa). Its wings will be very small. Thirty minutes, however, will be enough time to pump fluid and expand the wings. Now it is ready for its first flight.
Once the cycle has finished, it will restart as the butterfly lays more eggs. Pollinating the country is what these creatures will continue to do.
The Butterfly Life Cycle
Butterflies are insects which have four colorful wings. Butterflies have wings that are made up of tiny scales. Scientists estimate that there are between 15,000 and 20,000 different species of butterflies. Butterflies taste with their feet. The butterflies undergoes a complete metamorphosis. Metamorphosis means where a change occurs because the young are different from their parents.
Stage 1: The egg
First, it starts when a female butterfly lays her egg on leaves or stems of a plant. Inside these really tiny eggs, the caterpillars grow. The size of the egg is like the size of a sesame seed. The time it takes for the egg to hatch can also vary-in some species, this might take a few weeks.
Stage 2: The caterpillar
Once ready, the caterpillar leaves its egg. When it comes out it’s about 2 millimeters long. The caterpillar soon afterwards, eats its whole egg. Next, they start to chomp on leaves. During this stage, they shed their skin 4 or 5 times while they are growing. A fully grown caterpillar can be 100 times bigger that when it emerged from its egg!
Stage 3: The pupa
When the caterpillar is fully grown t forms itself into a pupa (or chrysalis). They usually change into this process on a twig in a hidden areas, so they can hide from predators. The ‘pupa’ stage might take a few weeks several months depending on the species. During this time, a hardened case forms around the pupa.
Stage 4: The butterfly
Once the butterfly is ready to emerge, the case around the pupa splits open. The butterfly is still not ready to fly away because the wings are really wet, soft and wrinkled, so its waits for them to dry. Once it’s ready to fly, the butterfly searches for flowers to lay eggs. This means the process starts again.
Now you know how a butterfly life cycle looks like.
