Describing of life cycle of a butterfly The picture illustrates the four-stage life cycle of a butterfly. It clearly seen that in the each stage are observed differences of butterfly’s life: from egg condition to state of butterfly. In the first stage, adult butterfly lays egg of larva on mulberries leaves and after some time from egg appears a caterpillar (or more simply “larva”) in the form of a worm with legs. Then, during several days, the larva begins to create a cocoon (pupa or chrysalis) around self with assist a special substance that called “silk thread”. This pupa provides protective cover for safe development and formation of butterfly during some periods. Finally, after staying certain time in the chrysalis, a butterfly goes out from pupa and leave cocoon for beginning a new life process. Thus, this cycle constantly continuous in the nature for formation a butterfly from egg. Each stage is extremely important for completely healthy formation of adult butterfly.
