摘要

Odonates (dragonflies and damselflies) have increasingly been used in understanding species responses to habitat modifications. Here, we reviewed historic odonate records from a tropical district, Pune, from India, and investigated changes in Odonata composition based on primary and secondary data to recreate an account of 180 years of odonatological research. The primary survey was carried out in 52 localities of Pune district from January 2019 to December 2022. We retrieved secondary data from 25 published articles and citizen science records. The dataset was divided into geographical boundaries of Pune Municipal Corporation (PMC) and the rest of PMC. Further, we divided the dataset into two types of time boundaries, namely, pre- and post-2010 and time era-wise (mid-nineteenth century, early-twentieth century, late-twentieth century, and early-twenty-first century). We registered a total of 98 species belonging to 52 genera and 10 families from the district (damselflies 36 and dragonflies 62). The PMC region represented 66 odonates under 36 genera and 7 families. Of the 98 recorded species, 70 species under 41 genera and 9 families were recorded during the present survey. Libellulidae was the most speciose family representing 38 species, followed by Coenagrionidae (21), Gomphidae (11) and Aeshnidae (8). Hills were found to be the biodiversity refugia with high species richness within the PMC boundary. Since the mid-nineteenth century there has been an increasing trend in reports of species records from the district primarily due to the rise of sophisticated citizen science platforms. Comparisons of pre- and post-2010 lists suggest the absence of 8 and the recording of an additional 27 odonate species. Perhaps changing land use, rapid urbanization, and data gaps are important factors giving rise to such patterns. Here, we uncover patterns in the odonate records from Pune city and recommend systematic long-term monitoring to identify areas of conservation concern. Our study provides data useful for planning management of urban green and blue spaces of the city.
