Why Are Fireflies Disappearing? The Scientific Explanation and Extinction Threat

Complaints from netizens about the difficulty of finding fireflies in the open recently are not merely childhood nostalgia. The phenomenon of the disappearance of these luminous insects has a strong scientific basis and serves as a serious alarm for the health of our ecosystem.

Prof. drh. Upik Kesumawati Hadi, a lecturer and entomology researcher from the School of Veterinary Medicine and Biomedical Sciences (SKHB) at IPB University, asserts that fireflies are bioindicators. This means the presence or absence of these insects reflects the environmental quality of an area.

“When environmental quality deteriorates, their population will quickly shrink or even disappear,” said Prof. Upik. She added that this decline has become a worrying global phenomenon.

Data from the International Union for Conservation of Nature (IUCN) reinforces these concerns. In Southeast Asia, including Indonesia, several species inhabiting mangrove areas are now categorised as vulnerable.

According to Prof. Upik, there are several crucial factors causing fireflies to “vanish” from our environment. Prof. Upik warns that if this trend of damage continues, future generations may only be able to see fireflies through books or digital media. However, the public can still contribute through simple steps.

“The conservation of fireflies is highly dependent on the preservation of their habitat. Protecting the environment means ensuring that the natural light of fireflies can still be enjoyed by future generations,” she concluded.
