Se analizan los sustratos de emergencia de Cordulegaster boltonii en un río del centro de la Península Ibérica. Para ello se recogieron exuvias en un tramo de 60 m de longitud. El 86% de las exuvias estaban sobre vegetales y las restantes sobre rocas del cauce. En la zona analizada las larvas seleccionaron positivamente para emerger plantas de la familia Cyperaceae, principalmente Carex y Eleocharis. Ninguna exuvia se localizó en árboles, tanto troncos como raíces fuera del agua.
Abstract: The main emergence substrates of the Golden-ringed dragonfly Cordulegaster boltonii in an Iberian river were analyzed. A total of 50 exuviae were collected from a stretch of river (60m) located in the center of the Iberian Peninsula. Plants were used by larvae as an emergence platform in 86% of cases, and rocks in the remaining cases. The most commonly used plants were Cyperaceae species (Carex and Eleocharis), and no exuviae were found on trees or tree roots (alder, Alnus glutinosa was the only tree species available).
