Aportació al coneixement de la fauna odonatològica del massís de Sant Llorenç del Munt i la serra de l'Obac Authors Xavier Maynou i Señé Abstract An updated list of 28 species of Odonata recorded in the Sant Llorenç del Munt Massif and Obac Range (Catalonia) in 2007 and 2008 is provided, with an estimation of the degree of presence of each species. The list of species is compared to existing records, old and recent. The speciesdiversity observed in this study is similar to that in other Catalan nature reserves, although most of the species found here can be considered ecological generalists. In this survey, data regarding reproduction and phenology are also provided for every species, the most important dragonfly sites are identified and actions for the conservation and improvement of the Odonata community richness are suggested.
