Life cycles – Clip

The video explains the lifecycle of giant mayflies, which spend three years developing as larvae in a river. Once they hatch into adults, they cannot feed due to the absence of mouths, giving them only a few hours to find a mate before dying. Female mayflies live just long enough to lay their eggs safely.

Describe the process that giant mayflies undergo from larva to adult.

What is the primary purpose of the adult female giant mayflies' short lifespan?
