Daily Diet of Pelobates fuscus (Pelobatidae, Amphibia) in the Khoper River Floodplain (Saratov Region)

The daily diet of Pelobates fuscus in local populations in the Khoper river floodplain is considered. The absence of gender differences in their daily diet is shown. Most of P. fuscus prey is made up of animals weighing 10–25 mg and having body lengths of 8–18 mm. Hymenoptera (70.8%) and Coleoptera (52.1%) predominate by the number of specimens and by biomass, respectively. The number of daily caught invertebrates usually does not exceed 15. The lowest feed consumption is in April and October, while the highest one is in the summer months.
