Odonata (Insecta) diversity of Kuldiha Wildlife Sanctuary and its adjoining areas, Odisha, eastern India

Journal of Threatened Taxa, 2018

A study was carried out to assess the Odonata fauna of Kuldiha Wildlife Sanctuary, Odisha, eastern India from November 2012 to October 2013. During the study a total of 54 species of odonates including 37 species of dragonflies (Anisoptera) and 17 species of damselflies (Zygoptera) were recorded. Among the dragonflies, the family Libellulidae was well represented with 30 species whereas among the damselflies, Coenagrionidae was well represented with seven species. Overall, the odonate fauna of Kuldiha Wildlife Sanctuary accounted for 49.09% of the odonate species known from Odisha and 10.73% of India. Therefore, further long-term studies on these lesser-known insect fauna in Kuldiha Wildlife Sanctuary will be useful in understanding their status over time.

A Checklist of Odonata (Insecta) of Dibrugarh District of Assam, India

Journal of Entomology and Zoology Studies

Dibrugarh district of Assam is situated to proximity to the junction of Eastern Himalayas and Indo-Burma Biodiversity Hotspots. Climatic conditions of the district support a very rich biodiversity, where Odonatdes (Dragonflies and Damselflies) are an important component. The present study was carried out in Dibrugarh district to document the status and distribution of odonates from April, 2019 to May, 2022. A total number of 81 species of odonates representing 54 genera and 11 families have been recorded in this study. Conservation status of the recorded species indicates that 69 species were under the category of Least Concern (LC), 7 species were Data Deficient (DD) and 1 species was Not Evaluated (NE). However, habitat destruction due to lack of awareness among the local people is the potential threat to the conservation of odonates in the district.

Diversity of Odonata in and around the Vivekananda Kendra Vidyalaya ( NEC ) , Baragolai , Margherita , Tinsukia district of Assam ( India )

2016

A total of 39 species of Odonates, including 28 species of dragonflies(sub-order: Anisoptera) belong to 3 families and 11 species of damselflies(sub-order: Zygoptera) belonging to 3 families were recorded in and around the Vivekananda Kendra Vidyalaya (NEC) Baragolai, Margherita, Tinsukia district of Assam(India) between March, 2015 to June, 2016. From the sub-order Anisoptera, Libellulidae was the richest family with 25 species and from the sub-order Zygoptera, Coenagrionidae is the richest family with 9 species. A detail list of odonates recorded from the study area is presented.

Diversity of Odonata (Insecta) in Padmatola wetland, Balasore, Odisha, India

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 fami-lies and suborder zygoptera represented by 18species with 9 genera from 3 families. Family Libellulidae be-longing 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.

Diversity of some odonatans insects in Kota, Rajasthan, India

Journal of entomology and zoology studies, 2019

Order Odonata is an important group of insects as it includes ecologically and environmentally valuable species. Odonata are ecological indicators. Studies on diversity and distribution of fauna are prerequisite of biodiversity conservation. In the present study attempt has been made to enlist dragonflies and damselflies in four different areas of Kota: Karani mata, C.V. garden, Bhitariya Kund and Yatayat Park. The study was conducted from September 2014 to August 2016. Present investigation revealed the presence of 12 species of Odonata belonging to 2 families (Libellulidae, Coenagrionidae). In the study area the most dominant family was Libellulidae (7 species) and Coenagrionidae (5 species). The abundance of species was also recorded. Out of the 12 species recorded in 4 survey areas 3 species are abundant, 7 species are occasional and 2 species are rare in the study site. The study indicates a rich and diverse fauna in the survey area.

Odonata fauna with their status of Achanakmar-Amarkantak Biosphere Reserve, Madhya Pradesh and Chhattisgarh.

The paper reports detailed entomological survey on the dragonflies and damselflies (Odonata) diversity in Achanakmar-Amarkantak Biosphere Reserve. During the course of study 70 species of Odonata belonging to 12 families is provided. The highest number of Odonate were recorded belonging to the Libellulidae (31 species), followed by Coenagrionidae (15), Gomphidae, (5), Protoneuridae (3) and Lestidae , Aeshnidae (4 species), Platycnemididae (2 species), Calopterygidae and Chlorocyphidae (2 species) and Euphaeidae, Corduliidae and Macromiidae (one species). Of the total 67 species 23 were very common, 21 were common, 18 rare and 5 very rarely in occurrence. The observations support the high value of this Achanakmar-Amarkantak Biosphere Reserve for conservation of Odonata and research on their biology.

A Checklist of Odonates (Dragonflies & Damselflies) of Upper Brahmaputra Valley Zone of Assam, India

CERN European Organization for Nuclear Research - Zenodo, 2022

A checklist of the odonates (dragonflies and damselflies) occurring in the upper Brahmaputra Valley Zone of the state Assam from gathered published work is presented in this paper. The scientific name, common name, distribution and the conservation status of the species were compiled in tabular form. Odonates diversity in the upper Brahmaputra Valley zone of Assam comprised of 101 species under 11 families. In the region, Anisoptera (Dragonflies) were dominant with 55 species over Zygoptera (Damselflies) with 46 species.

Diversity and community structure of Odonata (Insecta) in two land use types in Purba Medinipur District, West Bengal, India

Journal of Threatened Taxa

The present study recorded a total of 45 species of Odonata, of which one species, Ischnura mildredae, was recorded for the first time from West Bengal in India. Thirty-eight species were found in Tamluk Municipality as compared to 21 species in Haldia Industrial Belt (IB), with 14 species common to both the localities. Index of similarity revealed that the two localities were slightly dissimilar in odonate faunal composition as only 47% of species were shared. In both the localities, Anisoptera was more abundant, comprising over 69% of the total odonates. Libellulidae was the most abundant Anisopteran family in both the localities, comprising over 66% of the total odonates. Coenagrionidae was the most abundant Zygopteran family in both the localities. Thirteen species of Anisoptera and 11 species of Zygoptera were found only in Tamluk whereas two species of Anisoptera and five species of Zygoptera were found only in Haldia IB. Crocothemis servilia, Pantala flavescens, and Ce...
