The post-monsoon abundance was comparatively high. It was observed that the suborder Anisoptera was dominant with 28 species under 3 families. Suborder Zygoptera revealed 18 species under 4 families. Libellulidae was the species rich family (24 species), followed by the Coenagrionidae (12 species), Platycnemididae (3), Lestidae (2), Aeshnidae (2), Gomphidae (2), and Chlorocyphidae (1). Of the 46 species, 13 were very common, 22 were common, 10 rare and one very rare.

Though the post- monsoon abundance of Odonata was high but Odonata diversity was greater in pre-monsoon period when the food and nutrition were abundant. In the present study it is found that Libellulidae is the richest family with maximum number of species (10 species) which is followed by family Coenagrionidae (4 species), Platycnemidae (2 species) and Ashnidae (1 species). The area therefore can be considered as a species rich diversity site in a purely urban backdrop.

The present investigation is based on extensive survey of all three habitats during three major seasons (pre-monsoon, post-monsoon and winter). A total of 4,268 individuals belonging to 68 species in 39 genera under 9 families were recorded during the study period (December 2011-December 2015). Family Libellulidae (44%) was the most dominant and widely distributed in different sampling sites in all the three habitats. The most dominant species was Pantala flavescens(18.35 %). Across the three land-use types, there was a difference between the species composition with forest being the most diverse followed by urban habitat and agricultural land, though, the abundance of species were much more in urban habitat. Clustering analysis showed that urban and agricultural lands are more similar forming the same clusters whereas forest forms a different one. Species richness and abundance varied with seasons, post-monsoon being highest in richness as well as abundance. Variation in rainfall patterns has been reported to be one of the important factors. During the present investigation, a total of 52 species were reported from Bhimashankar Wildlife Sanctuary (WLS), and out of which 40 species were new records from the area. A total of 37 species was documented from Ujani Wetland, out of which 21 species have been recorded first time. Thus the present work aims to document the Odonate diversity of the Pune district along with their habitat selection and seasonal variations which provides baseline data that can be used for their conservation strategies.

The objective of this study was to find out the diversity and abundance of Odonates and to evaluate the importance of human-managed urban parks and gardens in supporting Odonata diversity. Thirty big and small parks and gardens of Pune city were surveyed during 2012-2013 at regular intervals to record the diversity of Odonates. A total of 1113 individuals were recorded comprising of 33 species under 6 families. The diversity and abundance of species depends on a number of factors like presence or absence of water bodies, size of the water bodies, level of human disturbances, shade cover, presence of emergent aquatic reeds, degree of pollution and garden management practice.
