The central theme of this study is to assay diversity of damselflies in the Victoria Park reserve forest, Bhavnagar city, Gujarat. (21°44’48” N 72°7’54” E) It is a favorable habitat for diversity of damselflies. The seasonal investigation carried out during the period of two years, particularly in monsoon season, 2014 to 2015.
