     we investigated the winter food of mediterranean horseshoe bats (rhinolophus euryale) in four winter cave roosts in southern slovakia and northern hungary and investigated the relationship between food and ambient temperature. the bats were active during the whole winter period and they produced excrement throughout the entire hibernation period, even when outside temperatures dropped below zero. the guano was in two forms, containing (1) prey items and (2) non-prey items. the identifiable items belonged to lepidopteran species, but only one was identified, on the basis of the genital fragments, the moth colotois pennaria, which was the main prey species in autumn and early winter. our results shed light on the extraordinarily high level of activity in this bat species during winter hibernation, which in temperate regions is a strategy that enables bats to survive when prey is reduced or absent. in r. euryale, the torpor in the course of hibernation is not continuous and our results help to explain how energy losses caused by bat movements are covered.
