The diagram delineates the developmental stages of a fly’s life cycle, illustrating the progression from the egg stage to that of a mature adult capable of reproduction.
Overall, the fly’s life cycle encompasses six stages, with an average duration of two to four weeks from inception to maturity, culminating in the emergence of a fertile female.
The life cycle commences when the female fly deposits eggs, which incubate for a period ranging from 8 to 24 hours before hatching. Upon hatching, the organism enters the first larval stage, soon progressing to the second larval stage within approximately 4 to 7 days, during which time the larvae undergo substantial growth and development through feeding.
Subsequently, the larva transitions into the third stage, continuing its maturation until it metamorphoses into a pupa. This pupal phase, lasting between 10 to 20 days, involves extensive internal transformations in preparation for the adult stage. Eventually, the young adult fly emerges, reaching sexual maturity approximately 20 days post-emergence, thus completing the reproductive cycle as a fully developed egg-laying female.
