Butterfly Metamorphosis


Butterfly Metamorphosis

Metamorphosis is the process of a caterpillar into a new animal (perfect phase) of the butterfly. In the process there long enough and long however the simple. First of all start ari eggs in place by a butterfly on a leaf (usually the leaves of citrus trees or other trees can also) which aims to eventually leaves can be a caterpillar food until it reaches adulthood when it was time to pupa / chrysalis and in few days will be a new butterfly.



 EGG
Eggs will hatch between 3-5 days, larvae will walk to the edge of the leaves of host plants and start eating it. Some larvae consume the egg shell is empty as his first meal outside the skin of the larvae does not stretch to follow its growth, but when it becomes very tight larvae will change the skin.

LARVA (WORM)
► After hatching the larvae will feed most larvae consume the empty egg shells as a first food. Outer skin of the larvae does not stretch to follow its growth, but when it becomes very tight larvae will change the skin.
► The number of skin changes during larval life is generally 4-6 times, and the period between the turn of the skin are called instars.
► Larvae of butterflies vary in shape, but in most cylindrical, and sometimes have hairs, spines, tubercles or filaments.
► When the larvae reach maximum growth, the larvae stopped eating, went looking for the nearest shelter, attach themselves to twigs or leaves with woven yarn. The larvae have entered the phase of pre pupa and release the last time the skin to form pupae.

PUPA  (COCOON)
► Phase pupa when viewed from the outside like the rest period, whereas in the pupa occurs the formation of the perfect insect. Pupae are generally hard, smooth and form a structure without limbs. In general, the pupa is green, brown or color according to the surroundings. (Camouflaged). The formation of butterflies in the pupa usually lasts for 70-20 days depending on the species

BUTTERFLY
► Once out of the pupa, the butterfly would crawl to the top so that its wings are weak, wrinkled and slightly wet to hang down and expand normally. Immediately after the wings to dry, fluffy and strong, the wings will open and close several times and flight experiments.
► Phase imago or a butterfly is the adult stage
