New damselfly species
Why in News?
A new species of spreadwing damselfly named Lestes paloti has been officially discovered on 15 July 2026 in the western slopes of Kerala's Western Ghats.
Discovery and Taxonomy
- Scientific Name: Lestes paloti.
- Family and Order: Belongs to the family Lestidae under the order Odonata (suborder Zygoptera).
- Naming Tribute: Named in honour of Muhamed Jafer Palot from the Zoological Survey of India for his extensive work on regional fauna.
- Key Holotype: A male specimen collected in 2020 at Taliparamba, Kerala, serves as the primary name-bearing reference.
Unique Physical Characteristics
- Seasonal Colour Transformation: The species displays striking variation, changing from brown during the dry season to bluish during the monsoon.
- Microscopic Distinctiveness: Differentiated from its closest relatives strictly through internal structures, including the male anal appendages and a unique preapical notch on the cercus.
Habitat and Distribution
- Geographic Spread: Documented across six districts of Kerala: Kannur, Kozhikode, Wayanad, Malappuram, Palakkad, and Ernakulam.
- Unusual Microhabitat: Unlike common damselflies that dwell near open water, Lestes paloti prefers hidden scrub vegetation around homesteads and laterite hillocks.
- Cryptic Nature: Its secretive habits and physical camouflage are the main reasons it remained undetected for decades.
Ecological Significance
- Ecosystem Bioindicators: Damselflies are highly sensitive to pollution and environmental changes; monitoring them helps track freshwater health and forest degradation.
- Natural Pest Control: They function as critical aerial predators that feed on mosquitoes and minor farm pests.
- Conservation Alert: These discoveries underline that the Western Ghats' biodiversity is still not fully documented, emphasizing an urgent need to shield its fragile forest networks from infrastructure and climate stress.
