When people think of Nepal, towering peaks, fluttering prayer flags, and exotic birds often come to mind. Yet, tucked within its forests, grasslands, and alpine meadows lies another vibrant world that often goes unnoticed—the world of insects and spiders. For years, there has been a lack of awareness and funding for research on these creatures in Nepal. Only recently, with initiatives such as the annual butterfly count, is public attention slowly turning toward the incredible diversity of insects that thrive in this Himalayan nation.
A Landscape That Nurtures Diversity
Nepal’s geography is unique—it stretches from the subtropical lowlands of the Terai to the icy summits of the world’s tallest mountains. This dramatic change in altitude and climate creates an exceptional range of habitats, each home to its own fascinating insects and spiders. Just as birdwatchers flock to Nepal for its avian life, those curious about smaller creatures will find the country no less rewarding.
Beyond the Leech
Ask most trekkers about insects in Nepal, and they’ll recall the tiger leech (Juka)—infamous for its persistence during the monsoon season. But to limit Nepal’s insect life to leeches alone is to miss the true beauty of its ecosystems.
Wonders That Dazzle
The Firefly (Junkiri): Summer nights in rural Nepal glow with fireflies sparkling like strings of Christmas lights across the hillsides—a spectacle that feels almost magical.
The Krishna Peacock Butterfly (Papilio krishna): Nepal’s national butterfly, a rare swallowtail with shimmering green and blue wings, is a prize sighting for nature lovers.
Kaiser-i-Hind (Teinopalpus imperialis): Called Samrat Patanga in Nepali, this “Emperor of India” butterfly is one of the most striking in Asia and is globally threatened, making it even more special.
Atlas Moth (Attacus atlas): Among the largest moths in the world, with wings that resemble snake heads at the tips—a fascinating natural defense.
Praying Mantises (Dhyaney Kirā): Nepal is home to several charismatic mantis species, such as the Indian Grass Mantis (Schizocephala bicornis) and the Giant Asian Mantis (Hierodula patellifera), masters of camouflage blending perfectly into leaves and grasses.
Jumping Spiders (Fudkine Mākhura): Nepal hosts many dazzling jumping spiders. Most remarkable is Euophrys omnisuperstes, the Himalayan jumping spider—a tiny survivor that lives at elevations of up to 6,700 m (22,000 ft), including on Mount Everest, making it a candidate for the highest known permanent resident on Earth.
Tarantulas of the Hills (Thulo Mākhura): In the warmer southern regions, tarantulas can be found—impressive, hairy spiders that are more gentle than their reputation suggests.
Why They Matter
Insects and spiders are not just background characters in nature—they are essential. They pollinate crops and wildflowers, recycle nutrients, control pests, and form a vital link in the food chain. Their presence—or absence—can tell us much about the health of Nepal’s fragile ecosystems.
For Observers and Photographers
Whether you are a trekker who pauses to notice the shimmer of a butterfly on a rhododendron trail, or a macro photographer eager to capture the sparkle of a spider’s eyes at dawn, Nepal has endless discoveries waiting. The more we learn about these creatures, the more we realize that their beauty and ecological importance deserve the same attention we often reserve for birds and mammals.
Nepal is not just a land of mountains—it is a land alive with wings, colors, and eight-legged wonders. The next time you walk its trails, look a little closer. A whole hidden world is waiting.
