Gurung sees no reason why Pokhara cannot do the same.“Why should mountains be our only attraction?” he asks.Indeed, the Back To Nature Resort on the western edge of Phewa Lake is already doing just that. One humid monsoon night this week, the blinking lights of hundreds of fireflies made the forest glow, while the lucky few who had heard of the place gasped with awe.“We have tried not to publicise this too much, we want to practice sustainable eco-tourism,” says the resort’s Dambar Pun. “In fact, we now have domestic tourists who come here from all over Nepal, and even extend their stay. They cannot get enough of the fireflies.”The firefly’s blinking glow is a mechanism for mating and scaring off predators, and only happens a few weeks in a year in June-July. It therefore can be a part of a package of attractions for Pokhara visitors during the monsoon, Pun says.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022111015118/636d05f39c7e80680e0a5f37jpeg.jpg" alt="" width="1568" height="1000"><figcaption></figcaption></figure><a href="https://edition.cnn.com/2020/02/03/world/fireflies-extinction-risk-scn/index.html" data-saferedirecturl="https://www.google.com/url?q=https://edition.cnn.com/2020/02/03/world/fireflies-extinction-risk-scn/index.html&amp;source=gmail&amp;ust=1625458802773000&amp;usg=AFQjCNH2HlYNBoGHEyWSICYgypPFoH-wNQ">Fireflies are actually beetles</a> from the family Lampyridae and have been in existence since the age of the dinosaurs.

Across the world and in Nepal, poets and singers have waxed eloquent about the blinking light of the nocturnal insects.But for <a href="https://www.nepalitimes.com/banner/the-fading-light-of-nepals-fireflies/" target="_blank" rel="noopener noreferrer">a creature so admired</a>, there has not been much of an effort to study and protect them. As elsewhere in the world, firefly numbers have declined sharply, even prompting the International Union for the Conservation of Nature (IUCN) to set up a Firefly Specialist Group in 2018.“We grew up playing with fireflies, chasing them around Tundikhel, but those days are long gone,” laments Tirtha Bahadur Shrestha, a noted Nepali naturalist. “Fireflies need a pristine environment, and their very presence signifies undisturbed nature.”Fireflies belong to a family of beetles called Lampyridae and evolved alongside dinosaurs 100 million years ago. But habitat destruction, <a href="https://archive.nepalitimes.com/article/nation/pesticide-laced-vegetables-continue-to-poison,1555" target="_blank" rel="noopener noreferrer">rampant pesticide use</a>, light pollution and climate change now threaten to put the lights out on all 2,200 species of fireflies so far identified.Read also: <a href="https://www.nepalitimes.com/banner/between-existence-and-extinction-in-nepal/" target="_blank" rel="noopener noreferrer">Between existence and extinction in Nepal</a>, Sonia AwaleThe decline of fireflies indicates a degradation of the ecosystem, <a href="http://archive.nepalitimes.com/news.php?id=18976" target="_blank" rel="noopener noreferrer">especially of wetlands</a>. Yet, there has been no systematic study of the status, scope and habitat of these glow worms  in Nepal.“The number and diversity of firefly species are unknown in Nepal and researchers have not given priority to these insects,” says Hum Gurung of Singapore-based Birdlife International Asia, who is promoting firefly tourism in Malaysia, and developing a participatory citizen scientist group to study fireflies in Nepal.Gurung says firefly conservation must begin with first researching them and planning a sustainable eco-tourism model based on firefly viewing, just like the cherry blossom season in Japan or fall colours in New England.“Their commercial value will add to the efforts to protect them,” he adds.But in Nepal, these lightning bugs that were once ubiquitous in gardens, jungles, riverbanks, and even streets and playgrounds in the towns have all but disappeared. Where did they all go?In Pokhara, butterfly researcher Surendra Pariyar says: “I have nostalgic memories of fireflies from my childhood, but as the city’s concrete jungle spreads I hardly see even one firefly these days.”Read also: <a href="https://archive.nepalitimes.com/page/what-is-the-buzz" target="_blank" rel="noopener noreferrer">What's the buzz?</a>, Sonia AwaleElsewhere in Japan, Southeast Asia and South America, the charismatic beetles with their bioluminescent courtship displays have turned into a major attraction for nature and wildlife tourists.Extra income from the firefly boat tours was crucial in curbing overfishing in Malaysia’s Kuala Selangor. Fireflies can promote unique, insect-based <a href="https://www.nepalitimes.com/banner/nepals-other-attraction-the-night-sky/" target="_blank" rel="noopener noreferrer">night tourism</a> with indigenous communities in Bardia and Chitwan in Nepal.Says butterfly expert Bhaiya Khanal, previously with the Natural History Museum: “Firefly tourism opens up a lot of opportunities including the possibility of finding more species. This, in turn, will promote their conservation.”Artificial light however is the biggest threat to fireflies as it reduces the beetle’s breeding success. Bright lights from buildings, vehicles, flashlights, and even cell phones can disrupt firefly mating.Nurturing and protecting the habitat is equally important, especially as the bugs spend most of their life cycle in a larval stage and require several months or even up to three years, to develop into adults.“We need to understand their lifecycle and its role in the ecosystem, what it feeds on and what preys upon them and our conservation and ecotourism efforts should take all of these into account,” adds Tirtha Bahadur Shrestha.Fireflies can be a ‘gateway bug’ to get tourists and locals interested in conserving many other insects, often ignored in favour of tigers, rhinos and wild elephants. Nepal is a model for wildlife conservation but its efforts in protecting smaller organisms are nearly non-existent.But first, proper conservation mechanisms must be put in place so that spreading firefly tourism does not end up destroying the very insect it is trying to save.<a style="font-size: 15px; letter-spacing: 0.01em;" href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/csp2.391?utm_source=mp-fotoscapes" target="_blank" rel="noopener noreferrer">A new study</a> published in the journal Conservation Science and Practice provides the first comprehensive review of the geographic scope, magnitude, focal species, and other attributes of the major firefly tourism sites worldwide.The rapid proliferation of firefly tourism could mean new threats such as inadvertent trampling of female adults and degradation of larval habitats during tours.“Ultimately we have to change our destructive development methods and work on urban planning that takes into account the health of an ecosystem,” adds Hum Gurung, also co-author of the paper.Bhaiya Khanal agrees that conservation and development should go hand-in-hand. He says, “New infrastructure projects must not ignore these creatures, we must proactively protect them before they are forever gone.”<h2>What makes them glow?</h2><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd96e9c7e80680e092e9djpeg.jpg" alt="" width="1280" height="850"><figcaption> </figcaption></figure>Fireflies have a romantic morse code for every occasion, whether it is to find a mate, or to scare off predators. It could be a steady glow or a flashing light, differing in duration, timing, colour, and repetition.All 2,200 identified species have their own blinking codes, glowing to varying degrees during the larva stage but most lose their light-emitting capacity by adulthood. Fireflies are also active during the day when they use chemical signals or pheromones to attract partners.Fireflies also emit a lightning signal when threatened by predators, or to protect territory. The light comes from a chemical reaction called bioluminescence, and the glow is not hot, but cold to touch.The lower abdomen of a firefly consists of calcium, magnesium, and a naturally occurring chemical called luciferin. But it is a superoxide ion, an extra electron, that is responsible for pale yellow, green, sometimes orange or blue flickers during hot summer nights.The reaction can be harmful to living tissue, but it does not affect the insect because the reaction is contained and happens quickly. The toxic luciferin molecule could be the key to a breakthroughs in cancer research and therapy.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd9729c7e80680e092e9ejpeg.jpg" alt="" width="447" height="285"><figcaption> </figcaption></figure><h2>Fireflies in Nepal</h2><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111156/636cd9749c7e80680e092e9fjpeg.jpg" alt="" width="2093" height="1372"><figcaption> </figcaption></figure>Only three species of fireflies have ever been recorded in Nepal, and even those were when the first British naturalists came to Kathmandu in the 1830s.Diaphanea marginellus was spotted at 2,000m in Kavre, so was Luciola ovalis. But the most common species found throughout Nepal is Luciola cruciate, pictured above.Fireflies prefer hot and humid conditions and are therefore found in the plains and the mid-mountains valleys of Nepal between July-August-- in ponds, streams, marshes and rivers. Fireflies usually are not found above 1,200m altitude, so Kathmandu would be at the upper limit of their habitat.

Across the world and in Nepal, poets and singers have waxed eloquent about the blinking light of these nocturnal insects.But for a creature so adored, there has not been much of an effort to study the science and chemistry behind their luminescence, their distribution, or why they have declined sharply in number.Indeed, the bugs that were once ubiquitous in gardens, jungles, riverbanks, streets and playgrounds in Nepal have all but disappeared. Where did they all go?Fireflies belong to a family of beetles called Lampyridae and existed alongside dinosaurs 100 million years ago. But habitat destruction, rampant pesticide use, light pollution and climate change now threaten to put the lights out on all 2,200 species of fireflies so far identified.Fireflies are also ecologically important species as their decline indicate the degrading quality of wetlands. And yet, there is no detailed study about the status of the species in Nepal, their scope and habitat."Thousands of firefly species are found globally but the number of species and their diversity are unknown in Nepal. This is sad and researchers have not given any priority to these insects," says Hum Gurung, Regional Project Manager with Birdlife International Asia who is promoting firefly tourism in Malaysia.In the recent years, these charismatic beetles have turned into a major attraction for nature and wildlife tourists. In fact, their bioluminescent courtship displays draw over one million tourists annually to sites located in at least 12 countries, mostly in the Southeast Asia and North America.A new study published on the journal Conservation Science and Practice provides the first comprehensive review of the geographic scope, magnitude, focal species, and other attributes of the major firefly tourism sites worldwide.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111152/636cd8349c7e80680e092e2ejpeg.jpg" alt="" width="893" height="796"><figcaption>Tourism threatens many stages in the firefly life cycle.</figcaption></figure>Gurung, who is a co-author of the study, says that the rapid proliferation of firefly tourism provides a timely opportunity to examine how such activities may impact local firefly populations, and to highlight the biological factors that make certain species especially vulnerable to tourism-associated threats.Here in Nepal, fireflies can promote a unique, insect-based night tourism that also promote the sky at night. These can bring economic, social, and psychological benefits to local communities and tourists alike.Fireflies can also be a ‘gateway bug’ to get tourists and locals alike interested in conserving many other insects, often ignored in favor of large and small charismatic mammals.But first, proper conservation mechanism must be put in place so that spreading firefly tourism does not end up destroying the very insect it is trying to promote and save.<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110111152/636cd8379c7e80680e092e2fjpeg.jpg" alt="" width="2456" height="1632">“In Mexico, the rapid growth of firefly tourism over the past decade is thrilling but also alarming,” says co-author Tania López-Palafox. “We’re glad people can experience one of the world’s greatest natural wonders. But we also want to make sure the fireflies are still around for future generations to enjoy.”Lead author Sara M Lewis (co-chair of the IUCN SSC Firefly Specialist Group formed in 2018) of the Tufts University has spent three decades studying fireflies and highlights the need to recognise ecological requirements across all firefly life stages.The report further recommends minimising light pollution (bright lights from buildings, vehicles, flashlights, and even cell phones can disrupt firefly courtship rituals) to promote breeding success of firefly adults and protecting nearby habitat as the bugs spend most of their life cycle in a larval stage and require several months or even years to develop into adult form.In some sites, firefly populations have been threatened by tourists inadvertently trampling females and degrading larval habitats during their visits. A well-managed tour with trained guides is a prerequisite for sustainable firefly tourism. So is local communities educated about and motivated to protect firefly populations.Says co-author Wan F A Jusoh: “Local communities are the guardians of fireflies, and their stories and local knowledge carry the power to help protect them.”
