摘要
We studied the diet of two sympatric species of leaf-frogs, Phyllomedusa rohdei and P. burmeisteri, captured in a cacao plantation in the Atlantic forest domain of southern Bahia, using stomach-flushing. The most important prey categories for P. rohdei were Araneae, larval Lepidoptera and Orthoptera, while for P. burmeisteri: Araneae, Coleoptera and larval Lepidoptera. Other items frequently flushed out of the frogs were plant remains, mites and skin. The snout-vent-length of the frogs was not correlated with the length and number of prey items. Our results suggest that both leaf frog species studied are opportunistic sit-and-wait predators with a high overlap in prey categories.
