New Damselfly Species Discovered in Western Ghats

Why in News?

New Damselfly Species in Western Ghats: Researchers have documented multiple new damselfly species from the Western Ghats of Kerala between 2023 and 2026, reinforcing the region’s status as one of the world’s richest biodiversity hotspots. Notable discoveries include Lestes paloti, Euphaea wayanadensis, Melanoneura agasthyamalaica, Protosticta armageddonia, and Protosticta sanguinithorax, along with several other odonate species recorded from Silent Valley National Park.

Odonata and the Western Ghats

Odonata is the insect order comprising dragonflies and damselflies. While dragonflies are generally robust fliers, damselflies have slender bodies, delicate wings, and are commonly associated with streams, wetlands, forest pools, and riverine ecosystems. Because they are highly sensitive to changes in water quality and habitat conditions, odonates are considered important bioindicators of freshwater ecosystem health.

The Western Ghats, a UNESCO World Heritage Site and one of the world’s eight “hottest” biodiversity hotspots, supports an extraordinary diversity of endemic flora and fauna. Protected areas such as Silent Valley National Park, Peppara Wildlife Sanctuary, and the Wayanad landscape continue to yield new insect discoveries, demonstrating that the region remains scientifically underexplored.

Recent New Damselfly Species in Western Ghats Discoveries

Among the latest findings, Lestes paloti was discovered in Kerala’s Western Ghats and described in the International Journal of Odonatology in July 2026. Earlier, Euphaea wayanadensis, commonly known as the Wayanad Torrent Dart, was formally described in 2025 from the Wayanad region and published in the journal ENTOMON. Researchers also identified Melanoneura agasthyamalaica (Agasthyamalai Bambootail) near Peppara Wildlife Sanctuary and Protosticta armageddonia (Armageddon Reedtail) from the southern Western Ghats. Surveys conducted in Silent Valley National Park further recorded several rare odonate species, highlighting the park’s ecological significance.

Importance for Conservation

The discovery of these New Damselfly Species in Western Ghats highlights the exceptional biodiversity of the Western Ghats and underscores the need to conserve its freshwater habitats and forest ecosystems. Continued scientific exploration not only improves understanding of India’s insect diversity but also supports conservation planning in one of the country’s most ecologically sensitive landscapes.
