Why do bugs swarm over water? – Luke M. Jacobus
The lesson explores the fascinating life cycle of mayflies, particularly their brief adult phase during which they swarm over water to reproduce. With a lifespan of just a day or even minutes, mayflies have evolved to prioritize egg production, carrying thousands of eggs to ensure their species’ survival. Their presence in freshwater ecosystems is crucial, as they serve as a key food source for fish and indicate water quality, making them important indicators of environmental health.
