Anamalai Tiger Reserve home to 8 firefly species, first genetic study in State
A year-long study by the Tamil Nadu Forest Department and the Advanced Institute for Wildlife Conservation (AIWC), Vandalur, has identified eight species of fireflies in the Anamalai Tiger Reserve (ATR). This marks the first systematic study in the State where genetic analysis was undertaken to confirm different species. The study, conducted from April 2024 to March 2025, covered dense forests and agroecosystems. Researchers identified species like Abscondita perplexa, Abscondita terminalis, and Asymmetricata humeralis, and found that light pollution and pesticide/water pollution contribute to the decline of firefly populations, highlighting fireflies as indicator species for wildlife health.
Key Points
- A year-long study in the Anamalai Tiger Reserve (ATR) identified eight species of fireflies, marking the first genetic analysis of fireflies in Tamil Nadu.
- The study, conducted by the Tamil Nadu Forest Department and AIWC, provides a benchmark for future research on firefly distribution and abundance.
- Fireflies are considered indicator species for wildlife health, and their populations are threatened by light pollution, pesticide use, and water pollution.
- Abscondita perplexa, one of the identified species, showed a preference for darkness and avoided certain colored lights.
- The research underscores the importance of minimizing light pollution around forest and wildlife areas to protect natural animal behaviors.
