Daytime diet of the lesser sac-winged bat (Saccopteryx leptura) in a Colombian Pacific Island

Insectivorous bats represent more than half of all the Chiropterans world. Although they are important stabilizers insect populations within their habitat due to feeding habits, just few studies have been focused on diet insular bat species. The lesser sac-winged bat, Saccopteryx leptura, is widely distributed in new world tropics, but little known about its prey selection. In this study we determined composition population S. leptura from Gorgona Island, Colombia, using stomach and intestinal content samples. We our research atypical daytime behavior evaluate differences selection considering two main factors: 1) plant canopy cover 2) sex. found representatives nine orders insects, with Hymenoptera, Coleoptera Hemiptera as most consumed according abundance volume percentage. identified records at genus level leptura´s diet, Camponotus (Formicidae) Trigona (Apidae). general terms, did not find between covers nor sexes. However, when analyzing percentage by order, there were significant consumption Psocoptera both factors. Our results suggest that has an opportunistic tend feed a wide range sizes, usually abundant available environment.
