Fireflies, with their bioluminescent rears, are fascinating species that appeal to people’s imaginations, especially those of children. In Sri Lanka, the first systematic study of fireflies was carried out by British naturalists in the 18th century, but afterward, there was a loss of interest in studying these fascinating creatures.
Shedding new light on Sri Lanka’s firefly fauna, researchers and at least one enthusiastic amateur continue to study them today, resulting in several discoveries. Sri Lanka is home to 16 firefly species, while Abscondita perplexa and Asymmetricata humeralis are more common and show a countrywide distribution. In 2022, research on A. humeralis conducted by Dammika Wijekoon and Hemantha Wegiriya of the University of Ruhuna showed that male A. humeralis can look different in color and pattern, highlighting that there can be more secrets in the world of fireflies to be investigated.
