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 191st 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.
