Abstract:
Sixty-eight localities from Pune district, Maharashtra, India were surveyed for diversity, assemblage and
seasonal distribution of Odonata along three different habitats viz. agricultural land, forest and wetlands, and
urban. 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.
