Dineshkumar B. P., . and Venkatesha M. G., . and Ramakrishna S., . (2010) Biodiversity of odonates of the Bangalore region India. [Proceedings Paper]

Biodiversity of odonates in the Bangalore region was studied during 2003-2006. The study was conducted in selected six major lakes in and around Bangalore. During the study period 20 species of dragonflies under 15 genera and six species of damselflies under four genera were recorded. Of the 20 species of dragonflies populations of Brachythemis contaminata Crocothemis servilia servilia. Orthetrum sabina sabina and Trithemis aurora were abundant almost throughout the year. However. other species viz. Tramea limbata Ictinogomphus rapax Orthetrum pruinosum neglectum Anax parthenope parthenope and Brachydiplax sorbina were less in number and occur throughout the year. In addition a few species such as Acisoma panorpoides panorpoides Aethriamanta brevipennis. Rhyothemis variegata variegata Tramea basilaris Trithemis kirbyi kirbyi and Trithemis pallidinervis were found only during some seasons. Of all the dragonflies Pantala flavenscens was the most abundant species throughout the Bangalore region during September-April. Among the six species of damselflies Ceriagrion coromandelianum and Ischnura senegalensis were abundant almost throughout the year. However Lestes elatus Lestes praemorous Pseudagrion rubriceps rubriceps and Pseudagrion microcephalum were rarely seen only during some seasons of the year in specific lakes. The diversity and ecology of odonates are discussed.

Abstract

Biodiversity of odonates in the Bangalore region was studied during 2003-2006. The study was conducted in selected six major lakes in and around Bangalore. During the study period 20 species of dragonflies under 15 genera and six species of damselflies under four genera were recorded. Of the 20 species of dragonflies populations of Brachythemis contaminata Crocothemis servilia servilia. Orthetrum sabina sabina and Trithemis aurora were abundant almost throughout the year. However. other species viz. Tramea limbata Ictinogomphus rapax Orthetrum pruinosum neglectum Anax parthenope parthenope and Brachydiplax sorbina were less in number and occur throughout the year. In addition a few species such as Acisoma panorpoides panorpoides Aethriamanta brevipennis. Rhyothemis variegata variegata Tramea basilaris Trithemis kirbyi kirbyi and Trithemis pallidinervis were found only during some seasons. Of all the dragonflies Pantala flavenscens was the most abundant species throughout the Bangalore region during September-April. Among the six species of damselflies Ceriagrion coromandelianum and Ischnura senegalensis were abundant almost throughout the year. However Lestes elatus Lestes praemorous Pseudagrion rubriceps rubriceps and Pseudagrion microcephalum were rarely seen only during some seasons of the year in specific lakes. The diversity and ecology of odonates are discussed.
