Incomplete Metamorphosis of Praying Mantises

The video explains the process of incomplete metamorphosis in insects, focusing on the three stages: egg, nymph, and adult. It describes how some insects lay eggs in masses, leading to the emergence of nymphs, which resemble adults but undergo several molts before reaching full size. The final stage is the adult stage, where insects stop growing and develop wings. The video highlights the primary role of nymphs in finding food and their effectiveness as predators.
