The objective of the present study is to explore the diversity of dragonflies and damselflies (Odonata) in Athagarh Forest Division, Odisha. Odonates were studied from January 2015 to March 2015. In this survey a total of 56 species of odonates were recorded, including 31 species of dragonflies (Sub order: Anisoptera) belonging to 3 families and 25 species of Damselflies (Sub order: Zygoptera) belonging to 5 families. Among these species, Libelluidae and Coenagrionidae were the dominant families with maximum number of species being 26 and 17 respectively.

Dragonfly and damselfly (Odonata) species diversity was studied in the Bor wildlife sanctuary from 2011 to 2018. A total of 72 species of odonates belonging to 8 families were recorded. The study adds three new species for the Vidarbha region. The highest number of odonates belonged to the family Libellulidae (31 species) followed by Coenagrionidae (15 species), and Aeshnidae (six species). Of the total, 30 species were very common, 18 were common, seven were frequent common, 11 rare and six very rare. Among all, six species were Data Deficient, Indothemis carnatica (Fabricius, 1798) is listed as Near Threatened and 64 were Least Concern, in IUCN red-list of threatened species. The observations support the value of the wildlife sanctuary area in providing valuable resources for Odonata.

A study was carried out in Nalsarovar Bird Sanctuary to evaluate community composition of Odonates (Dragonflies and Damselflies) in Nalsarovar Bird Sanctuary (Ramsar Site), Gujarat. Transects survey was carried out at Nalsarovar Bird Sanctuary covering all habitats. Each transect was repeatedly surveyed in all seasons. A total of 30 species of dragonflies and damselflies were encountered belonging to 5 families namely Libellulidae, Gomphidae, Aeshnidae, Coenagrionidae, and Lestidae during the entire study. During the study, percentage frequency of occurrence, abundance and density of Odonates were calculated based on data collected to evaluate community composition of Dragonflies and Damselflies in Nalsarovar Bird Sanctuary. During the entire survey, the percentage frequency of occurrence of 3 species namely Brachythemis contaminata, Pantala flavescens and Trithemis pallidinervis were recorded highest. The most abundant species encountered were Pantala flavescens followed by Trithemis pallidinervis, Brachythemis contaminata, Ischnura aurora and Ischnura senegalensis respectively among all species encountered during the survey. However, the density of Odonates species namely Trithemis pallidinervis were highest which was further followed by Pantala flavescens and Brachythemis contaminata, Ischnura senegalensis and Ischnura aurora respectively during the entire survey. This study can be used as a benchmark for future conservation and monitoring of Odonates in state and similar wetland worldwide.

Insects belonging to the order Odonata are ecological indicators and studies of insects show that, certain species exhibit high association with particular ecological conditions. Panvel is one of the fast-changing metro city in Navi Mumbai, Maharashtra, India, due to ongoing construction of Navi Mumbai International Airport (NMIA), rampant urbanization, industrialization and unplanned development have resulted into ecological disturbances and habitats fragmentation. Literature review suggest that no baseline data is available with respect to Odonata, particularly of dragonflies and damselflies. Hence present study is undertaken. 15 species of Odonates representing 2 suborders, 2 families and 2 subfamilies. Recorded Odonates belongs to families Libellulidae & Coenagrionidae and species of family Libellulidae are found to be more abundant in the study area.

Dragonflies and Damselflies (Insecta: Odonata) of Hirpora Wildlife Sanctuary are presented. The Sanctuary is located in the District Shopian of Kashmir Valley (33°39'28.6"N 74°41'15.2"E). The area is rich in both floral and faunal diversity with most of the area covered with lush green forests. Around the sanctuary, Agro and Horticultural plantations such as Apple, Pear, Peach and vegetable crops abides most of the land cover in the area. The present study was carried out from June to October 2020. A total number of 10 species from six families were recorded in and around the area. The most abundant species recorded are from the family Libellulidae which are active mostly in the months from June to October. A number of freshwater bodies flow through the district and receives annual precipitation of around 1800mm, which makes the area more suitable for the Odonates diversity. Here we present the first preliminary report of order Odonata collected from the sanctuary and adjoining areas of Kashmir Valley.
Dragonflies and damselflies (Odonata) of Silent Valley National Park, Kerala, India and its environs
Entomon, 2024
The odonate diversity of the Silent Valley National Park (SVNP) in the Western Ghats (WG) of Kerala state, in southern India, is discussed. A total of 111 species of odonates (41 Zygoptera and 70 Anisoptera) including 29 endemics were recorded for the SVNP region, out of the 181 species (14 families, 87 genera with 68 WG endemics). SVNP harbours 53.37 per cent of WG and 61.34 per cent of the odonate diversity of Kerala. In addition, this includes 42.64 percent endemic odonates of Kerala and 35.80 percent of WG. With respect to IUCN Red List status, there were two vulnerable, three near threatened, 84 least concerned, 17 data deficient, and five species whose status was not assessed. Family Libellulidae (40 species) dominated the diversity, followed by Coenagrionidae and Gomphidae (16 species each). None of the species listed from SVNP is protected under the Indian Wildlife (Protection) Amendment Act, 2022.
Dragonflies and damselflies (Insecta: Odonata) of Jabalpur, Madhya Pradesh, India
Journal of Threatened Taxa, 2022
The present study was carried out to reveal the odonate diversity in Jabalpur city and its surrounding area in Madhya Pradesh, central India. During the study period of 2008–2019 a total of 75 species of odonates belonging to two suborders and nine families were recorded. Twenty-one new species were recorded for Jabalpur district and four for Madhya Pradesh; 37% (28) species were abundant or very common, 19% (14) were common, 16% (12) were frequent, 24% (18) rare, and 4% (3) very rare. The maximum number of odonates were found in family Libellulidae (n= 32), followed by Coenagrionidae (n= 17), Gomphidae (n= 09), Platycenemididae (n= 06), Aeshnidae (n= 05), Lestidae (n= 03), Macromiidae (n= 02), and Chlorocyphidae (n= 01). Of 75 species recorded from Jabalpur city, 72 come under the IUCN Red List. Among them, Indothemis carnatica come under Near Threatened (NT) category, 65 species come under Least Concern (LC) Category, six species under Data Deficient (DD), and three species remain not assessed. The study supports the value of the city area in providing habitat for Odonata.

The present paper deals with the study of species richness and diversity of butterfly fauna in the in the experimental garden. The population trends of butterflies were monitored for one year using transects counting method. A total of 66 species of butterflies belonging to five families and 47 genera were recorded during the study period. The family Nymphalidae showed the maximum species richness, comprising of 15 genera and 23 species, followed by Lycaenidae (14 genera, 14 species), Pieridae (8 genera, 12 species), Hesperiidae (8 genera, 9 species) and Papilionidae (2 genera, 8 species). A total of 1164 individuals were recorded of which Eurema hecabe (Linn.) was the most dominant species of butterfly in terms of number of individuals (38) followed by Junonia atlites (36). From the conservation point of view, the study area is undisturbed and rich in butterfly fauna.
