Older than the dinosaurs: scientists finally unlock secret of the mayfly’s dance
The bizarre vertical flight pattern has long puzzled experts but new research reveals why it may play a crucial role in the insect’s survival
TL;DR
- Male mayflies perform a vertical flight pattern, flipping over and descending like skydivers to identify females within swarms.
- This behavior helps males avoid pursuing non-female objects and ensures their limited mating time is spent effectively.
- Mayflies are among the oldest winged insects, with their basic design remaining largely unchanged for approximately 300 million years.
- New research published in the Journal of Experimental Biology used 3D filming to analyze mayfly flight paths and explain the mating ritual.
- Many mayfly species are declining due to pollution, sediment runoff, reduced river flows, and rising water temperatures.
- A riverfly census in Britain found a significant loss of mayfly species in chalk streams compared to 1998 levels.
- Scientists are concerned about an 'insect apocalypse,' with a significant percentage of insect species declining globally.
