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 2010, the researchers recorded Curtos costipennis for the first time in Sri Lanka, making it the first firefly member of the genus Curtos found in Sri Lanka.
Taking the first step, Wijekoon published the book "Fireflies of Sri Lanka," which is the first-ever comprehensive book on the taxonomy and ecology of fireflies in Sri Lanka, addressing the long-felt need and research gap in firefly literature in the country.
