Contribution of the participants of 4th Balkan Odonatological Meeting to the knowledge of Odonata distribution in Bosnia and Herzegovina (Dejan Kulijer, Iva Miljević & Jelena Jakovljev)

As a result of increased interest in dragonflies and close cooperation between odonatologists on the Balkan Peninsula, the Balkan Odonatological Meeting (BOOM) has been established in 2011. This report presents the results of the field trip during 4th Balkan Odonatological Meeting that was held in Bosnia and Herzegovina from 1st to 8th August 2014. With 69 surveyed localities and 496 records of 47 species, this was the most successful BOOM until now. The noteworthy results are records of several nationally rare species: Chalcolestes viridis, Coenagrion scitulum, Erythromma najas and Ceriagrion tenellum, and new populations of Cordulegaster heros, a species mentioned in the Annexes of the EU Habitats Directive. The distribution of Chalcolestes spp. in Bosnia and Herzegovina is also presented and discussed.
