Odonatologists have reconfirmed the presence of the elusive dragonfly species Crocothemis erythraea in the southern Western Ghats.
About Crocothemis erythraea Dragonfly:
- Species Type: A rare dragonfly species, usually found in Europe, Asia, and the Himalayas.
- Recent Finding: Reconfirmed in the Western Ghats, specifically in Kerala and Tamil Nadu high ranges.
- Comparison: Closely resembles the common lowland species Crocothemis servilia, leading to earlier misidentifications.
- Habitat Preference: Inhabits cooler, high-altitude areas above 550 metres.
- Historical Origin: Likely spread to South India during the Ice Age and survived in montane habitats such as Sholas and grasslands.
Significance of the Discovery:
- Biodiversity Insight: Demonstrates how ancient climate changes influenced current biodiversity patterns.
- Ecological Importance: Reinforces the Western Ghats’ status as a biodiversity hotspot of global value.
- Conservation Message: Highlights the need to protect sensitive high-altitude habitats like Sholas and montane grasslands.
