The study presents data on the food composition of Horváth’s toad-headed agama, Phrynocephalus horvathi, in northern slopes of Mount Ararat (Aralık, Iğdır). A total of 294 prey items were determined in the digestive systems of 36 (8 males, 11 females, and 16 juveniles) individuals examined in the study. Prey groups in the food composition are included in Aranea (1.4%), Orthoptera (1.0%), Hymenoptera (73.5%), Coleoptera (23.1%) and Diptera (1.0%). No significant difference was observed between sexes regarding food composition. Consequently, Phrynocephalus horvathi is partially myrmecophagous (73.5%) and an active predator.
