Older than the dinosaurs: scientists finally unlock secret of the mayfly’s dance
Scientists have uncovered the reasons behind the unique vertical flight pattern of mayflies, which may be crucial for their survival. This behavior helps male mayflies distinguish between males and females in their swarms, ensuring effective mating during their short lifespan. However, many mayfly species are declining in Britain, highlighting concerns about the broader insect population crisis.
- ▪Mayflies have existed for around 300 million years, long before dinosaurs.
- ▪New research reveals that male mayflies use vertical flight to identify females in their swarms.
- ▪Many mayfly species in Britain are declining due to pollution and habitat loss.
