The first verifiable photographic evidence of the rare spoon-tailed duskhawker dragonfly has been recorded in Arunachal Pradesh's Namdapha National Park.

  • The spoon-tailed duskhawker (Gynacantha basiguttata) was identified in Namdapha National Park.
  • This discovery enriches India's official Odonata checklist.
  • The identification was made through high-quality photographic evidence rather than physical collection.

In a significant boost to India's biodiversity records, the first verifiable photographic evidence of the spoon-tailed duskhawker (Gynacantha basiguttata) has been recorded in Arunachal Pradesh. This discovery, made within the 1,985 sq. km Namdapha National Park and Tiger Reserve, adds a rare and significant species to the country's dragonfly list.

The sighting occurred in October 2024 along the Miao-Vijaynagar Road. A team of five dedicated researchers observed a single male dragonfly hanging vertically from vegetation in a shaded area. While initially identified as Gynacantha khasiaca, a rigorous taxonomical correction revealed the specimen to be the spoon-tailed duskhawker, a species primarily associated with the Philippines and parts of Southeast Asia.

Scientific Identification and Features

The identification was based on detailed morphological features captured in photographs. Key identifiers included a distinctive black T-shaped mark on the frons, an olive-green thorax devoid of stripes, and unique wing pigmentation. Most notably, the species possesses narrow, expanded cerci that give the abdominal appendages a unique spoon-like appearance, hence its name.

This finding underscores the immense untapped biological potential residing within India's northeastern wilderness.

Why This Matters

BozokMedia analysis shows that this discovery is crucial for taxonomic accuracy in South Asia. Previous literature regarding the presence of G. basiguttata in India was considered doubtful as it relied solely on female specimens. The confirmation of a male specimen provides the scientific community with the definitive evidence needed to officially include the species in the national Odonata checklist.

The research, published in the Journal of Threatened Taxa, involved a collaborative effort from scientists across Karnataka, Maharashtra, Uttarakhand, and Arunachal Pradesh. Notably, the researchers adhered strictly to the Wildlife (Protection) Amendment Act, 2022, by documenting the species through photography without collecting physical specimens, setting a high standard for non-invasive field research.

Historical Background

The order Odonata, which includes dragonflies and damselflies, consists of predatory flying insects that serve as vital indicators of wetland health. For decades, certain species were thought to be absent from the Indian subcontinent due to lack of verifiable male specimens, making this find a breakthrough for regional entomology.

Did You Know?: Dragonflies are considered 'the faces of wetlands' because their presence often indicates a healthy and unpolluted aquatic ecosystem.
