Saffron Reedtail Damselfly Discovered in Karnataka

February 1, 2025

The saffron reedtail damselfly, scientifically known as Indosticta deccanensis, has been discovered in Madhugundi village, Chikkamagaluru district, Karnataka. This finding marks the first record of the species in the northernmost part of the Western Ghats. Previously, it was known to inhabit regions in Tamil Nadu and Kerala.

Species Characteristics

The saffron reedtail is a small damselfly, measuring less than two inches in length.
It has a distinctive cinnamon-coloured thorax and delicate, transparent wings.
This species is part of the family Platystictidae, commonly referred to as shadow damselflies.
Their slender and delicate appearance makes them challenging to spot without trained observation.

Habitat and Distribution

Saffron reedtails are typically found near slow-moving forest streams.
They thrive in areas with pristine water quality and thick vegetation.
The discovery in Madhugundi extends their known distribution northward, suggesting a broader ecological range than previously understood.
These insects are sensitive to environmental changes, making their presence an indicator of a healthy ecosystem.

Ecological Importance

The presence of the saffron reedtail indicates a clean and unpolluted habitat. Their lifecycle relies on the quality of water in their habitats. Therefore, protecting these areas from deforestation, water pollution, and climate change is crucial for their survival.

Research and Conservation

The discovery contributes to the understanding of biodiversity in the Western Ghats. The region is home to a rich variety of odonates, with 196 species identified, of which 175 are reported in Kerala. Odonates respond quickly to environmental changes. During the COVID-19 lockdown, their populations increased in urban areas, denoting their sensitivity to human activity.

Historical Context

The saffron reedtail was first described by British biologist Frank Fortescue Laidlaw.
This species is endemic to the Western Ghats and is not found in urban environments.
They are typically spotted during the monsoon months from June to November.
The local name for the damselfly in Malayalam is ‘kumkuma nizhal thumbi’.

Future Research Directions

Despite recent studies, much remains to be understood about odonates. Ongoing research is essential to uncover the ecological roles of these insects and their responses to environmental changes. The Society for Odonate Studies (SOS) continues to advocate for the conservation of these species and their habitats.
