Odonata

A recent study has revealed an alarming biodiversity gap in the Western Ghats, with researchers documenting only around 65% of the dragonfly and damselfly species historically recorded in the region. The findings indicate a potential decline of nearly 35% in these ecologically significant insects.

The survey, conducted between February 2021 and March 2023, covered 144 sites across five Indian States. Researchers recorded 143 odonata species, including 76 dragonflies and 67 damselflies. Among them, 40 species were found to be endemic to the Western Ghats, highlighting the region’s unique ecological importance.

About Odonata

Odonata is an order of predatory, carnivorous flying insects comprising more than 6,400 described species worldwide. It includes:

• Dragonflies (suborder Anisoptera)
• Damselflies (suborder Zygoptera)

Adult odonates are recognizable by:

• Two pairs of transparent wings
• Elongated bodies
• Strong flying ability

These insects play a vital role in aquatic ecosystems. Their larvae, known as nymphs, inhabit freshwater bodies where they act as efficient predators. As adults, they continue to help maintain ecological balance by controlling populations of mosquitoes and other small insects.
