Dragonfly Life Cycle and Characteristics

The video explains the life cycle of a dragonfly, which includes three stages: egg, nymph, and adult. It begins with the egg stage, where female dragonflies lay eggs in water or on aquatic plants. In tropical regions, eggs hatch in about 5 days, while in temperate areas, they hatch in spring. The nymph stage follows, where dragonflies live in water and use jet propulsion to move. They do not form cocoons before becoming adults. The adult stage features dragonflies with long abdomens, large eyes, and the ability to fly in various directions. They are predators of small insects. The video concludes with a call to subscribe for more content.
