In order to determine the diet of the cattle egret Bubulcus ibis (L. 1758), a study was carried out from January 2017 until July 2018 in two integral wetlands in El Kala National Park (PNEK). These two sites are included in the list of the Ramsar Convention on wetlands of international importance. They are located in northeast Algeria: Oubeïra Lake (36° 50' N, 08° 23' E) and Tonga Lake (36° 53’N, 08° 31’E). The results obtained on a total of 126 cattle egrets allowed us to detect among the ingested prey found in the stomach contents, one species of Orthoptera related to the Ensifera suborder: Sciobia (Scioba) bolivari (Chopard 1937) for the first time in Algeria. This work provided the first report on Sciobia (Scioba) bolivari.
