The diagram illustrates the various stages in the life cycle of a fly. We can see that the entire life cycle lasts between 35 and 48 days. It is also evident that there are five main stages in the development of the fly, from a mature egg-laying female to a young adult insect.
The life cycle of the fly begins when the female adult lays her eggs; typically, a female lays many eggs within 8 to 24 hours. Each egg transforms into a larva within 4 to 7 days. This early stage is divided into the first, second, and third phases of larval development.
During the third stage of the life cycle, the larva evolves into a pupa over the course of 10 to 20 days. After that, the pupa changes into a young adult over the next 20 days. Eventually, the young adult matures into a fully developed adult insect, capable of laying eggs. This cycle is then repeated as part of the fly’s life.
In summary, the average life cycle of a fly lasts about 2 to 4 weeks.
