Jugnu Are Disappearing: Is India Losing Its Fireflies?
There was a time when summer nights in Indian villages could look magical.
As darkness arrived, tiny lights appeared among trees, fields, bushes and grass.
Jugnu.
Fireflies were once a familiar part of rural life. Children watched them glowing in the darkness, while farmers and villagers saw them around fields and water bodies.
Today, many people say they rarely see them.
So an important question is being asked:
Are jugnu close to extinction?
The scientific answer is more complicated.
Fireflies as a whole are not currently classified as one single species that is close to extinction. India has remarkable firefly diversity, with a 2026 checklist documenting 92 species across 27 genera, and more than 60% of those recorded species are endemic to India.
But there is another worrying reality:
Firefly populations are declining in many places.
Why Are Jugnu Disappearing?
Scientists have identified several pressures affecting fireflies.
The biggest include:
- Habitat destruction
- Pesticide use
- Artificial light at night
- Urbanisation
- Climate change
- Water pollution
- Habitat fragmentation
A 2026 review of Indian fireflies identified habitat loss, pesticides, climate change and artificial light at night as important drivers of population decline.
The International Union for Conservation of Nature’s Firefly Specialist Group has also highlighted habitat loss, pesticide use, climate change, artificial lighting, unplanned urbanisation and water pollution as major threats.
The Problem With Modern Nights
One of the strangest threats to jugnu is something humans normally consider progress:
Artificial light.
Streetlights, buildings, advertisements, vehicles and bright homes have transformed the natural darkness of the night.
But fireflies depend on darkness.
Their flashes are part of their communication and mating behaviour.
When artificial lighting becomes too strong, their signals can become difficult to detect.
IUCN research on light pollution notes that artificial light can disrupt firefly communication and affect their ability to find mates.
In other words, we are making the night brighter—and potentially making it harder for fireflies to communicate.
Pesticides Are Another Major Threat
Fireflies are insects, so they can be affected by pesticides used in agriculture and other environments.
Their life cycle is also closely connected with soil, vegetation and water.
When these habitats are contaminated or destroyed, fireflies can lose the conditions they need to survive.
A 2025 review of Indian fireflies highlighted pesticide contamination and habitat destruction as important causes of decline and documented severe local population reductions in some regions.
This means that protecting fireflies is not simply about protecting one beautiful insect.
It is about protecting the ecosystems where they live.
Fireflies Are More Than Beautiful Lights
Many people think of jugnu only as a magical night-time insect.
But fireflies have ecological importance.
They are part of food webs, and their presence can provide information about environmental conditions.
Researchers describe fireflies as bioindicators, meaning changes in their abundance or behaviour can provide clues about changes in ecosystem health.
When fireflies disappear from an area, it may therefore be a warning that something else has changed.
Perhaps the wetland has disappeared.
Perhaps pesticides have increased.
Perhaps vegetation has been removed.
Perhaps artificial lighting has become too intense.
The missing fireflies may be telling us something.
Today’s Children May See Fewer Jugnu
Older generations in many parts of India remember seeing large numbers of fireflies.
Today, sightings can be much less common in urban and heavily developed areas.
Recent reporting from Telangana described fireflies as becoming increasingly difficult to see and linked their decline to ecological changes.
In Kerala, researchers and conservationists have similarly raised concerns about fireflies becoming increasingly rare in urban environments.
This does not prove that every Indian village has lost its fireflies.
Some forests, wetlands, farms and relatively undisturbed areas still support them.
But the trend is concerning.
Could Jugnu Actually Become Extinct?
For some individual firefly species, local extinction is already a documented concern.
But saying “all jugnu are close to extinction” would be scientifically inaccurate.
India’s firefly diversity is still being discovered and studied, and researchers say major knowledge gaps remain.
In fact, the 2025 review noted that Indian firefly species have not yet received comprehensive IUCN Red List assessments, highlighting the lack of detailed information about their conservation status.
So we should be careful.
The correct warning is:
Many firefly populations are declining, and some species or local populations may be at serious risk.
What Happens If We Lose Them?
Imagine a future where children know jugnu only from photographs.
They may read about the tiny insects that once illuminated village fields.
They may watch videos showing hundreds of fireflies flashing together.
But they may never experience it themselves.
That would be more than the loss of an insect.
It would be the loss of a natural experience.
The disappearance of fireflies would also indicate that important habitats have been heavily changed.
We Can Still Protect Them
Firefly conservation does not always require expensive technology.
Some simple actions can help.
Reduce Unnecessary Night Lighting
Turn off unnecessary outdoor lights.
Use shielded lights that illuminate only the required area.
Avoid excessive lighting around gardens, wetlands and natural habitats.
Protect Natural Vegetation
Fireflies need suitable vegetation and habitat.
Removing every bush, patch of grass and fallen leaf from an area can reduce the places where insects live.
Reduce Harmful Pesticide Use
Responsible pest management can reduce unnecessary chemical exposure to insects and other wildlife.
Protect Wetlands and Water Bodies
Many firefly species depend on moist habitats during parts of their life cycle.
Destroying wetlands can destroy their habitat.
Let Children Experience Nature
Instead of seeing every insect as a pest, children can learn to observe them.
A child who understands why a firefly matters may grow into an adult who wants to protect its habitat.
The Light Is Fading
The decline of jugnu is a small example of a much larger environmental problem.
Humanity is changing landscapes faster than many species can adapt.
We build more roads.
More buildings.
More lights.
More farms.
More cities.
More pollution.
And sometimes we notice the consequences only after something disappears.
The firefly gives us a beautiful warning.
When the natural world becomes too bright, too polluted and too crowded, even the smallest lights can disappear.
Will Future Generations Still See Jugnu?
Nobody can say that all jugnu will disappear.
That is not what the scientific evidence shows.
But there is enough evidence of population decline and habitat pressure to take the warning seriously.
India still has extraordinary firefly diversity.
That means there is something worth protecting.
The goal should not be to wait until a species reaches the edge of extinction.
The goal should be to protect its habitat before that happens.
One day, a child should still be able to walk outside on a warm Indian night, look toward a dark field and ask:
“Papa, what are those little lights?”
And the answer should still be:
“Those are jugnu.”
