Butterflies
Butterflies are
the most beautiful and enchanting insects in the world!
How the The Life Cycle of a
butterfly begins: the adult male butterfly and adult female
butterfly meet when flying around each other in a meadow for a short
time and then land on a flower to mate. The
adult male butterfly then flies away and the adult female butterfly
then finds a place to lay her eggs. The
female butterfly curves her long body in the direction of the leaf
and lays her very tiny eggs on the leaf (usually in the spring).
The eggs are made of a sticky substance so they won't roll away
or fall off the leave.
Around five to six days later
the larva (young stage) is then developed inside the egg which is
the butterfly’s
caterpillar stage.
One caterpillar will hatch out from each egg by chewing (eating)
its way out and this can take several hours. The caterpillar feeds
on its egg first and then moves on to eat from the plant in which
it was born.
The caterpillar is growing quickly,
the more it eats the bigger it gets. Eventually the caterpillar
will shed from its first skin and grow a bigger skin.. There is no
time for sleep for a caterpillar as it only has a few weeks to store
as much energy as needed to change into a butterfly.
It is now time for the the caterpillar
(larva) to then make a chrysalis (for butterflies)
or a cocoon (for moths). The caterpillar must find a sturdy
branch and spin some sticky silk threads to help it become secure
and hang onto the branch. It spins some thread around its
middle section (called the belt) and produces a patch of coiled
thread at its tail end (called the pillow). It's skin will
be shed for the last time and a shell will form underneath its
shed skin. This shell hardens into a protective case which
is the chrysalis. The caterpillar turns into a soft, squidy
jelly like blob.
After a few
weeks the caterpillar is changing into the body of the beautiful
butterfly. When the chrysalis turns clear it is time for the
butterfly to break free by pushing to split the chrysalis. The
butterfly is ready for its first
flight.
Once the butterfly breaks out
its wings are wet and crumpled. The butterfly then pumps blood
into its wings to help them to dry out and to expand. This
stage does not take long at all. Once its wings are dry the
butterfly is ready to fly away and search for flowers for food.
Not all butterflies hatch out of their chrysalis right away,
some spend the winter months inside and hatch out in the springtime. Most
butterflies have a short life (about a month) so it must find a
mate quickly to start the life cycle of a butterfly all over again.
There are several butterflies
that have longer lives (up to nine months). For these butterflies,
when winter arrives, they will hibernate by finding a safe shelter
in a shed, in a house or behind a plant (and go to sleep). When the
warm weather returns they will become active again. Butterflies use
the sun to elevate their body temperature. The adult will eventually
return to the plant or tree where it hatched and will lay its own
eggs to continue this reproduction (life-cycle) all over again.
Have a good look around your
garden this summer to see how many different butterflies you can
spot. Enjoy their beauty and remember to
be very gentle if you handle any as they are very fragile.
