Good morning, everyone! I was in trouble and unhappy, I won’t to write in my blog for long time. Chinese New Year is passed, spring is arrived in
The day
after was a sunny day. I was walking in
a garden, there was many butterflies flying between the plants and
flowers. I like butterfly, it likes a
girl wear a gorgeous dress dance in the garden.
Butterfly is not only has meaning of the person pursue pleasure or
changeable people, but also has beautiful image as a fantastic girl or an angel
represents a wonderful story and blessing.
Butterfly (farfalla) is an insect, it has six walking legs, 3 body
parts, a pair of antennae, compound eyes, and an exoskeleton. The three body
parts are the head, thorax and abdomen. It is flying insect with large scaly wings. The life of a butterfly is
marked by four vastly different stages: egg, caterpillar, pupa, and adult. The
egg hatches into a caterpillar, which immediately feeds on the leaf of the
plant where it has hatched.
The caterpillar grows
and molts, shedding its exoskeleton when that becomes too small. After four to
six molts, the caterpillar pupates or transforms. Butterflies pupate in a
chrysalis. Butterflies do not form cocoons. The pupa or chrysalis is soft at first
but in about an hour, the shell hardens to protect the growing butterfly
within. It’s a beautiful shade of green to help disguise it from predators. The
pupa has no eyes, antennae or legs but inside a complete metamorphosis is going
on. The mouth changes from what the caterpillar needed to chew milkweed leaves
into a straw-like tongue that the butterfly will need to sip nectar from
flowers. It grows wings about two weeks.
Finally, the shell bursts open and a butterfly emerges. It has four wings which are tiny, wet and wrinkly, after a couple of hours it can fly. The butterfly pumps body fluid, called hemolymph, into the wings to make them grow big and strong. After the wings have hardened, it’s time to eat! The butterfly flies off in search of its first meal, which it will slurp up through its straw-like tongue or proboscis. After just dining on milkweed, butterflies enjoy a little more variety and take their nectar from several different flowers, making them one of nature’s migratory pollinators.
Butterflies are cold
blooded and must depend on their environment for heat. To fly, their body
temperature needs to be greater than 75°F . On cooler days they often bask with outstretched
wings on a rock or other flat surface to store up heat energy. The dark
patterns on many butterfly wings help the insects absorb solar energy. On
cloudy, cool, or windy days, most butterflies remain in protected spots. You
are likely to spot them in warm, sunny, calm areas where flowering plants can
supply the butterflies with nectar.
Butterflies are attracted to flowers, they prefer purple, red,
yellow, orange, or pink blossoms; flat-topped or clustered flowers; and short
flower tubes. A well-planned butterfly garden has blooming flowers throughout
spring, summer, and early autumn. This provides a continuous food source and
plants of varying heights to accommodate large and small butterflies. A butterfly-friendly garden contains both adult nectar plants and
caterpillar host plants. A few common vegetables also serve as caterpillar host
plants. Butterfly gardeners plant extra vegetables, which is enough
for them and their caterpillars. As a bonus, butterfly gardens often attract
hummingbirds.
