The recent discovery of a new species of dragonfly in Assam, known as ‘Platygomphus benritarum’, has been generating buzz in the scientific community. This species has been named in honor of two women, Monisha Behal and Rita Banerji, who have made significant contributions to the ecology of Northeast India.
Discovery and Naming of Platygomphus Benritarum
The Platygomphus benritarum was discovered by two researchers in June 2020 along the banks of the Brahmaputra in Assam. The male specimen found had freshly emerged, as suggested by its shimmering wings and abdomen. This dragonfly features distinctive turquoise-blue eyes and a hairy, dark brown face. The species was named after Monisha Behal, founder member of Northeast Network (NEN), and Rita Banerji, founder of Green Hub, to acknowledge their pioneering work in the region.
Habitat of the Discovered Species
The habitat where this dragonfly species was found mainly comprises grasslands, sparse trees, paddy fields, and marshlands. The area also features forest patches and tree plantations. The discovered dragonfly was spotted resting on a large tree about 5-6 metres away from the Brahmaputra riverbank.
Dragonflies: An Overview
Dragonflies along with damselflies belong to the insect order Odonata. The word “Odonata”, meaning “toothed ones”, encapsulates some of the most ancient and visually striking insects on Earth. They are also among the largest flying invertebrates known to exist. The order Odonata includes three groups: Anisoptera (which house dragonflies), Zygoptera (home to damselflies), and Anisozygoptera (a relict group with only two living species).
Characteristics and Role of Dragonflies
Dragonflies are aerial predator insects typically found around freshwater habitats across the globe. Their vivid colors make them attractive research subjects for both ecological studies and art. The majority of dragonfly species are tropical, particularly residing in rainforests. These insects play a crucial role as bio-indicators of an area’s ecological health due to their diet, which includes mosquitoes and other disease-vector insects such as those transmitting Malaria and Dengue.
Potential Threats to Dragonflies
Despite their ecological significance, dragonflies face numerous risks — primarily the rapid destruction of their natural habitats. This situation poses an immediate threat to their survival and underscores the urgent need for conservation efforts to protect these extraordinary creatures.
