Episode notes
Huge Species Diversity Matters
- There are over 2,600 firefly species with different habitat needs.
- Some species are abundant while others are rare and of conservation concern.
Weather Shapes Populations Over Years
- Weather across multiple years strongly affects adult firefly abundance.
- Larval stages last one to two years and poor conditions can delay pupation.
Urban Fireflies Are Remnant Survivors
- Urban firefly populations often persist as remnants of former forests.
- Conserving urban remnant habitats is crucial because lost populations are hard to restore.
