Diet composition of Boana crepitans (Anura: Hylidae) and Haddadus binotatus (Anura: Craugastoridae) in contrasting habitats of the Atlantic Forest, southern Bahia, Brazil

Boana crepitans is a widely distributed species, and in this study we described its diet. The study was carried out in southern Bahia, Brazil, where the species is abundant. The stomach-flushing method was used to obtain the stomach contents and release the specimens. We captured 26 specimens; 19 (73%) had stomach contents, and seven (27%) had empty stomachs. We identified 96 prey items; 69 were plant material, five were unidentified, and 21 were arthropods belonging to nine taxa, composed mainly of Coleoptera and Orthoptera. The diet of Haddadus binotatus was also described, captured in a Cabruca system, and comprised 36 individuals, 19 (52.7%) with stomach contents, nine (25%) without stomach contents, and eight (22.2%) whose contents were mucus or digested unidentified material. We identified a total of 48 prey items, which belong to 11 prey categories. Contrary to the literature, the items that most contributed were Blattodea, Araneae, and Coleoptera. The ingestion of larvae and Orthoptera suggests that B. crepitans and H. binotatus have a combination of active foraging behavior and sit-and-wait strategy, presenting a generalist diet.
