ABSTRACT

Here is described the diet of Proceratophrys boiei (Wied, 1825), a leaf litter frog of the Atlantic Forest, and test for relationships between frog size and prey size and type. The diet was determined by stomach content analysis. In 38 frogs, was found 76 prey items belonging to 23 taxa. Insects predominate in the diet and the most frequent categories were coleopterans (39.4% of total volume) and orthopterans (25.0%). There was a positive correlation between frog size and volume of prey taken. The most important ontogenetic shift in prey type was an increase in the consume of coleopterans and insect larvae with increasing frog size.

Key Words: Amphibia, Anura, Leptodactylidae, Proceratophrys boiei, food habits, litter frog, Atlantic Forest, Brazil
