ABSTRACT
We studied the trophical spectrum of Bombina variegata species from Vadu Cri┼čului, Bihor County. The study was realized during the period May-June 2005. We observed certain differences in feeding between males and females. At the same time there is a difference between the two periods of study. These differences may appear because of the temperature changes or because of the preferences of sexes for various preys. The feeding intensity is proportional with the temperature raising. The studied stomachs contain animal prey and at the same time we found vegetal fragments and shed skin. The most important preys for males were from Cladocera and Coleoptera order and for the females the biggest source of food was Coleoptera and Formicida.
