          Abstract

          Praying mantis and spider species are common food items in the diet of several anuran species. Nevertheless, in this study we report the predation of young treefrogs Osteocephalus taurinus by two spider species, a Pisauridae and a Trechaleidae (Neoctenus sp.) and by the praying mantis Eumusonia sp. in Mato Grosso, Central Brazil. The great abundance of this treefrog in the region, combined with its small body size during the juvenil stage, favor its predation by generalists predators. Indeed, more studies are needed to quantify the real influence of invertebrate predators on anuran populations.

          Espécies de aranhas e louva-a-deus são itens alimentares de diversas espécies de anuros. Porém, aqui reportamos a predação de jovens anuros da espécie Osteocephalus taurinus, por duas espécies de aranha, uma Pisauridae e uma Trechaleidae (Neoctenus sp.), e por um louva-a-deus Eumusonia sp. em Mato Grosso, Brasil Central. A grande abundância desse anuro na região, aliada a seu pequeno porte durante a fase juvenil, favorece sua predação por invertebrados generalistas. Entretanto, mais estudos devem ser conduzidos para quantificar a real influência de predadores invertebrados nas populações de anuros.
