Abstract
Libellulidae and Coenagrionidae are the most dominant families among dragonflies and damselflies. The present study deals with the diversity, occurrence and present status of libellulids and coenagrionids within the Regional Institute of Education Campus in Bhubaneswar, Odisha, India (RIEC). The major objectives of this study are to prepare a preliminary checklist of libellulids and coenagrionids species in the RIEC and to find out the status and distribution of genera and species in their respective families. This study is also aimed at systematic planning for developing different strategies for conservation of odonates in the campus. During this study a total of 24 species have been recorded out of which 20 species belong to the family Libellulidae representing 15 genera and four species belong to the family Coenagrionidae representing four genera. The findings of this study are based on the survey which was carried out for a period of four months in 2015.
