butterfly cycle

butterfly cycle

The growth of butterflies is different from all other insects.  It appears as a square cycle as follows: 1. egg stage, 2. slug stage, 3. pupa stage, and 4. maturity stage.

egg stage
In normal reproductive conditions, the female will mate with the male only once.  when mated  The female will find the spawn on the leaf.  and stems of food plants  Selecting food plants for eggs is a unique ability of the particular butterfly species.
The female butterfly spawning stage generally lays about one hundred eggs, with a lifespan of 5-7 days, and in this one hundred eggs does not spawn a hundred butterflies in nature.  The survival rate of butterflies to become beautiful winged insects is only 2%. The rest have to assume the role of prey for some birds and insects, or may be blown by the wind to fly their eggs to the end of the day.  front

glass body
The glass or caterpillar of a butterfly has a long body, 3 pairs of real legs, and several pairs of prolegs on the abdomen.  All for walking  when it turns into a butterfly  The prosthesis will shrink.  The real legs will grow into the legs of a butterfly.  The head of the glass has a biting type mouth, used to eat the leaves of its food plants.  which was different from when it turned into a butterfly.  which the mouth will change to a mouth that sucks (siphoning type) the color of this glass  It normally fits well with the environment in which it lives.  Therefore, they are all camouflage colors for the enemy's eyes.  in order to escape from enemies, especially birds.

The pupal stage  The pupae stage The pupae period of the common butterfly is about 5-7 days (about 20 days in the golden sac moth) after the caterpillars find a place to pupate.  will begin to build webs  The web is made up of filamentous glands inside the worm's mouth.  The web will serve to hold the pupae attached to the plant.  Each line connects to the body, as in the golden bag butterfly.

The adult stage
come out as a butterfly  by pushing the head out first  at the top of the pupa  As this new butterfly pushes out  I can hardly see that  How could it spread its wings?  Because of this newly created wing  It was folded in a pleated, fan-like manner and packed together tightly.  Wait a moment, the wings will slowly unfold.  with the butterfly still hanging  clinging to the remains of a chrysalis  by leaving the wings below  To rely on the gravity of the earth to help spread the wings. In addition, the body of the butterfly will be compressed.  to drive fluids inside the body  to flow into the wing line  Makes it spread its wings faster too.
During the time it spreads its wings  which takes about half an hour  If something is blocked, such as a wing attached to a branch,  or other things  making it unable to fully spread out. As a result, the butterfly's wings were forever crippled.  which will soon die on its own  because he can't fly to find food
Adult butterflies do not molt.  or increase the body size longer  It serves to breed and lay eggs.  To inherit the next generation only. Food that was eaten from the original changed to nectar from flowers instead.  General butterfly lifespan is about 10-20 days.
