Dragonfly Down, Pg18

Key Highlights:

• A study between 2021-2023 in the Western Ghats revealed a 35% decline in dragonfly species.
• Of 144 species surveyed, 40 were endemic, with several now missing.
• Dragonflies, ancient insects, have existed for 250-300 million years and are efficient predators.
• August is considered Dragonfly month in India, with about 500 species found nationwide.

Detailed Insights:

• Dragonflies, as nymphs, spend up to five years underwater, preying on small fish before transforming into aerial hunters.
• Endemic species are particularly vulnerable to habitat degradation, signaling broader environmental distress.
• The decline is attributed to pollution, infrastructure development, climate change, and irresponsible tourism.
• Dragonflies play a crucial role in controlling insect populations, and their disappearance indicates ecosystem imbalance.
• Conservation efforts and increased public awareness are needed to protect dragonfly habitats and prevent further decline.

Key Concepts Involved:

• Endemic Species: Species unique to a defined geographic location.
• Biodiversity Hotspot: Region with high levels of endemic species facing significant habitat loss.
