A group of researchers have discovered a new species of damselfly in the Wayanad landscape of the Western Ghats, Kerala.

Odonate species

Odonate species, commonly known as dragonflies and damselflies, are a group of insects belonging to the order Odonata.
Odonates are predatory insects with 4 wings and are known for their vibrant colors and agility in flight.
Suborders - Anisoptera (dragonflies) and Zygoptera (damselflies).
- Dragonflies (Anisoptera) - Typically, larger and more robust, with eyes that touch on top of the head and wings spread out at rest.
- Damselflies (Zygoptera) - Usually slenderer, with eyes separated and wings folded together along the body at rest.
Ecological Importance- Odonates play a crucial role in freshwater ecosystems as both predators and prey, helping to control populations of other insects, including mosquitoes.
Global Distribution- While they are predominantly found in warmer regions, some species thrive in habitats as far north as Canada.

It is Kerala’s 191^st recorded odonate species.
Family – Euphaeidae.
The team first observed the distinct morphotype of Euphaea wayanadensis at the Kalindi River, Thirunelli, in Wayanad district in 2013.
Morphology - A longer black hind wing patch, broader and uninterrupted humeral and ante humeral stripes in males, and unique structural traits in the male genital vesicle.
Genetic analysis also played a crucial role in confirming the species’ status.
Habitat - The species preferred fast-flowing streams with rocks and aquatic vegetation with evergreen and semi-evergreen tree growth on the banks to thrive.
