Diversity of Odonata (Insecta) in Padmatola wetland
The present study has been carried out in the Padmatola wetland of Balasore district of Odisha, India during December 2013 and May 2014. This study emphasises a checklist of total 51 species of odonata (Dragonflies and Damselflies). Among this the suborder anisoptera represented by 33 species with 22 genera from 4 families and suborder zygoptera represented by 18species with 9 genera from 3 families. Family Libellulidae belonging to anisoptera is dominant with 28 species and Coenagrionidae belonging to zygoptera is richest with 15 species. But the rapid degradation of the wetland by human activities are the main threat to the odonates along with the biodiversity.
Odonate Diversity of Some of the Wetlands of Yavatmal District Maharashtra India
Review Of Research , 2015
Odonates are ideal models for the investigation of the ecosystem health as they are efficient indicator of habitat degradation. They also play vital role in trophic level management as key component to maintain delicate balance in pray predator relationship. Being predators both at larval and adult stages, they play significant role in the food chain of the wetland ecosystem. Odonate fauna were surveyed from some of the wetlands of Yavatmal district, Maharashtra from July 2013 to May 2014 in pre monsoon, Post monsoon and winter season respectively. 38 species of odonata belongs to 2 Suborders and seven families have been recorded. Maximum diversity were contributed by familiy Libellulidae and Coenagrionidae followed by Protoneuridae, Platyenemididae, Lestidae, Aeshnidae and Gomphidae.

DIVERSITY ASSESSMENT AND EXPANSION OF ODONATA IN NARMADA BASIN OF JABALPUR REGION (M.P
ARTICLE INFO ABSTRACT An opportunistic survey of Odonata diversity and distribution was done in along with river Narmada region of district Jabalpur to give updated list of species within the study. Odonata play crucial role in ecosystem functioning and can be used as biological indicators as well as potential bio-control agent of environmental quality whereas biodiversity protection and conservation is a national and international agenda and responsible for sustainable development of a region or a country. A total of 38 species are recorded belonging to two sub-orders Zygoptera with 16 species and Anisoptera with 22 species. In order Odonata, Libellulidae with 17 species is the most dominating families among dragonflies and Coenagrionoidae with 13 species among damselflies while others have fewer representatives. Bargi dam shows the highest Regional diversity of Odonata in Jabalpur. The present study encourages the conservation of a wide range of dragonfly species in this area.

Dragonflies and damselflies (Insecta: Odonata) of the Kole Wetlands, central Kerala, India
2021
A year-long study was conducted at the Kole Wetlands, a Ramsar site in central Kerala to document the diversity of dragonflies and damselflies and understand their seasonality. Checklist survey method was used to sample adult odonates in 30 randomly chosen locations. A total of 44 species (30 dragonflies and 14 damselflies) belonging to 33 genera and eight families were recorded in the study area. Species richness showed a peak in the post-monsoon season and a dip in the summer. The observations support the value of the Kole Wetlands in providing valuable resources for Odonata.

A study on diversity of odonates was conducted at Kondajji Lake of Kondajji Village located in Harihar Taluk, Davanagere District of Karnataka. The study was conducted to explore status, diversity and threats of Odonates during February 2007 to January 2008. The study revealed a total of 34 species of Odonates in 24 genera belonging to 6 families have been reported. Among them Anisoptera (Dragonflies) dominated with 25 species, followed by the Zygoptera (damselflies) with 9 species. The family Libellulidae dominated with 20 species among the Anisoptera. Among the Zygoptera, Coenagrionidae was found to be the dominant family with 6 species. Based on the frequency of occurrence 35% of the species were common, 23% were very common, 21% were rare, 15% were occasional and 6% were very rare. According to IUCN categorization all the odonate species recorded from the study area comes under 'Least Concern' (LC) category. The study provides the baseline data on Odonates diversity of some major wetland water bodies of Davanagere District of Karnataka state for research on their biology and the conservation.
Diversity of Odonata (Insecta) in Rural and Urban Wetlands of Coimbatore, Tamil Nadu, India
A study was conducted to assess the diversity of odonata in the rural and urban wetlands of Coimbatore, Tamil Nadu, India from August 2018 to January 2019. A total of 4 wetlands from rural and urban were surveyed with a total of 8 families of 32 genera and 45 species were recorded. Among them, 8 families of 21 genera and 26 species from Kallar a tributary stream and 4 families of 20 genera and 25 species from Ukkulam lake of rural whereas 4 families of 15 genera and 18 species from Singanallur lake and 3 families of 9 genera and 10 species from Kurichi lake of urban. Among the anisopterans, Brachythemis contaminata (Fabricius, 1793) was abundant in the urban lakes, Pantala flavescens (Fabricius, 1798) in the rural stream and Diplacodes trivialis (Rambur, 1842) in the rural lake whereas in the zygopterans, Neurobasis chinensis (Linnaeus, 1758) dominated in the rural stream, and Ischnura aurora (Brauer, 1865) dominated over the lakes.

A study on diversity of odonates was conducted at Kundavada Lake located in Davanagere District of Karnataka. The study was conducted to explore status, diversity and conservation threats of Odonata from October 2010 to September 2011. During the study period, a total of 32 species of Odonates in 24 genera belonging to 6 families have been reported. Among them the order-Anisoptera (Dragonflies) dominated with 23 (72%) species, followed by the Zygoptera (damselflies) with 9 (28%) species. The family Libellulidae dominated with 19 species among the Anisoptera. Among the Zygoptera, the family Coenagrionidae was found to be the dominant with 6 species and least by the Lestidae with 1 species. Based on the frequency of occurrence of odonates, 37% of the species were common, 22% were occasional, 19% were very common, 16% were rare and 6% were very rare. The study highlights the importance of odonates and threats in their habitat due to different anthropogenic activities and also provides the baseline data on Odonate diversity of some major wetlands of Davanagere District of Karnataka state for research on their biology and the conservation.

The present attempt is to analyze the role of aquatic insects especially Odonates diversity in maintaining the status of the Komaranahalli wetland. The study was conducted from November 2012 to October 2013 during which, a total of 33 species of Odonates belonging to 6 families have been recorded. Among them order-Anisoptera (Dragonflies) was predominant with 24 species, followed by the Zygoptera (damselflies) with 9 species. Among the order-Anisoptera, the family Libellulidae was widely distributed and dominated with high percentage composition followed by the Coenagrionidae among order-Zygoptera i.e., 84%, (n=18) and 67% (n=6) respectively. The status based on the frequency of occurrence shown that 40% were common, 21% were occasional, 18% were very common, 15% were rare and 6% were very rare. The study highlights the importance of odonates and threats in their habitat due to different anthropogenic activities and also provides the baseline data of Odonate diversity of Davanagere District of Karnataka state for research on their biology and the conservation.
