Nutritional analysis indicates blow flies are high in protein and fat, making them a potentially valuable food source for birds like cardinals.
Life Cycle Stages
Blow flies, belonging to the family Calliphoridae, undergo a complete metamorphosis consisting of four distinct life cycle stages: egg, larva, pupa, and adult. Initially, the female lays eggs on decaying matter. These eggs hatch into larvae, also known as maggots, which feed voraciously. During the larval stage, they molt several times, growing rapidly. The next stage is the pupa, where larvae encase themselves in a hard shell, undergoing transformation. Finally, the adult blow fly emerges, ready to reproduce and continue the cycle.
Stage | Duration | Key Characteristics |
---|---|---|
Egg | 8-24 hours | Laid on decaying matter |
Larva | 3-9 days | Rapid growth, multiple molts |
Pupa | 3-20 days | Transformation to adult |
Adult | 2-6 weeks | Reproduction and dispersal |
This cyclical process guarantees blow fly survival and propagation.
