Butterfly

Butterfly is the animal here.









Here is the clasification of Butterfly :
  • Kingdom     : Animalia 
  • Phylum        : Arthropoda
  • Class           : Insecta
  • Order          : Lepidoptera
  • Superfamily : Papilionoidea
  • Family         : Nymphalidae
  • Subfamily    : Danainae
  • Tribe           : Danaini
  • Genus         : Danaus
  • Species       : D.plexippus
Butterfly like its named move by fly. They were slow. When they rest, it will so with its wings  held over body.
They are herbivore. The larval or caterpillar stage and the adult butterfly food preferences, largely due to difference in their mouth parts.Caterpillar are very particular about what they eat, which is why the female butterfly lays her eggs only on certain plants. Caterpillars don't move much and may spend their entire lives on the same plant or even the same leaf.

Caterpillar have chewing mouth parts, called mandibles, which enable them to eat leaves and other plant parts. Caterpillar do not need to drink additional water because they get all they need from the plants they eat. Adult butterflies are also selective about what they eat. Unlike caterpillar, butterfly can roam about and look for suitable food over a much broader territory. In most cases, adult butterfly are able to feed on various liquids. They drink through a tube - like tongue called a proboscis. It uncoils to sip liquid food, and then coils up again into a spiral when the butterfly is not feeding. Most butterflies prefer flower nectar, but others may feed on the liquids found in rotting fruit, in ooze from trees, and in animal clung. Butterfly prefer to feed in sunny areas protected from wind.

Butterflies can flourish in several different types of habitats, such as wetlands, meadows, wood 's edge, rainforest, and even an urban garden. Unfortunately, many natural butterfly habitats are being destroyed by the elimination of weeds and native grass from yards, chemical pesticides, parks and roadways, as well as the deforestation of  tropical rainforests, the native habitat. Butterfly lay eggs.

They are metamorphosed. 
There are four steps of butterfly complete metamorphosed.
1. Egg : The first stage of the butterfly life cycle is the egg or ovum.
Butterfly eggs are tiny, vary in color and maybe round, cylindrical or oval.

2. Larva : The larva or caterpillar that hatch from the egg is the second stage in the life cycle of butterfly.
Caterpillar often, but not always, have several pairs of true legs, along with several pairs of false legs or prolegs. A caterpillar ' s primary activity is eating. They have a voracious appetite and eat almost constantly. As the caterpillar continues to eat, its body grows considerably. The tough outer skin or exoskeleton, however, does not grow or stretch along with the enlarging caterpillar. Instead, the old skin is shed in process called molting and it is replaced by a new, larger exoskeleton. A caterpillar may go through as many as four to five molting before it becomes a pupa or chrysalis.

3. Pupa : The third stage is known as the pupa or chrysalis. The caterpillar attaches itself to a twig, a wall or some other support and the exoskeleton splits open to reveal the chrysalis. The chrysalis hangs down like a small sack until the transformation to butterfly is complete. However, it is within the chrysalis shell that the caterpillar ' s structure is broken down and rearranged into the wings, body and legs of the adult butterfly. The pupa does not feed but instead gets its energy from the food eaten by the caterpillar or the larva stage. Depending on the species, the pupa stage may last for a few days or it may last for more than a year. Many butterfly species overwinter or hibernate as pupae.

4. Adult : The fourth, final, and the most wonderful stage of the life cycle is the adult. Once the chrysalis casing splits, the butterfly emerges.
It will eventually mate and lay eggs to begin the cycle all over again. Most adult butterflies will live only a week or two, while a few species may live as long as 18 months.
Largely defenseless against many of these hungry predators, Lepidoptera have developed a number of passive ways to protect themselfes. One way is by themselfes inconspicuous through the use of camouflage. The enemies of butterflies are birds, spiders, lizards and various other animal.

Butterfly are not endangered.
