Abstract

The ant fauna of the Natural Park of the Aiguamolls de l'Empordà was studied with various methodologies. Three samplings have been carried out: the first one during the first fortnight of September 2008 with 200 pitfalls opened one week and sight hunting for an hour in fifteen areas of the Cortalet, the second one was on July 21, 2014 with 400 eppendorf with baits distributed in linear transects of 100 eppendorfs in four enclosures within the route of the Cortalet of the CBMS, and the last one during the months of September and October 2019 by sight hunting on the right and left banks of the Fluvià river and the lakes of Vilaüt. A total of 40 species were found grouped into 19 genera. The riparian forest is the vegetation type with the highest number of ant species. It is worth to note the presence of Tapinoma pygmaeum (Dufour, 1857) in riparian forest and meadows, and Chalepoxenus muellerianus (Finzi, 1922), also in a riparian forest, and unusually parasitizing an arboreal species, Temnothorax aveli (Bondroit, 1918).
