In May 2001 we collected droppings of Rhinolophus euryale from a colony located in the Basque Country (souhtwestern Europe). Simultaneously, we used Malaise traps to determine prey availability in different habitats, weighting it according to the habitat use of bats. Prey categories found in droppings were then compared to availability to perform the selection analysis. The main consumed prey were by far small lepidopterans (5-11 mm long), followed by tipulids, and scarabaeid beetles (entirely Rhizotrogus sp.). Moths and beetles were selected positively, whereas the other categories were underrepresented in the diet. These results suggest the importance of small moths in the pre-breeding diet of this species, although other items might seasonally play an important role.
