What are the four stages of flea metamorphosis?

The four stages of flea metamorphosis are accurately represented as egg, larvae, pupae, and adult. This cycle illustrates the complete metamorphosis that fleas undergo, which is crucial for understanding their life cycle in pest control.

In the first stage, the flea begins life as an egg, which is laid on the host or in the environment. The larvae hatch from these eggs and are worm-like creatures that feed on organic debris, including flea dirt and other organic material. Following the larval stage, fleas enter the pupal stage, where they form a cocoon and undergo transformation. Finally, they emerge as adults, ready to begin the cycle again by finding a host to feed on and reproduce.

Understanding these stages is important in pest control, as each stage may require different management strategies to effectively break the life cycle of fleas and reduce their population. The simplicity and accuracy of the correct option make it a fundamental aspect of flea biology that pest control technicians must grasp thoroughly.
