The horse flies of El Tarf Province, northeastern Algeria comprise 15 species within two subfamilies (Chrysopsinae and Tabaninae) belonging to five genera (Atylotus, Chrysops, Dasyrhamphis, Haematopota, and Tabanus). The genera Chrysops, Dasyrhamphis, and Haematopota are represented by two species for each, while the genera Atylotus and Tabanus are represented by four and five species, respectively. Seasonal abundance was assessed from mid‐March until the end of September, 2017 for the trapped species. Haematopota pluvialis and Tabanus autumnalis appeared in April and lasted until September with a peak in May. Atylotus agrestis appeared in May with the highest density and lasted until September. Atylotus fulvus, Atylotus kroberi, and Haematopota italica emerged in April with peaks in May, while Chrysops flavipes appeared in March, reaching its peak in May and June, declining in July, and disappearing thereafter. Atylotus flavoguttatus, Chrysops mauritanicus, and Dasyrhamphis tomentosus appeared in April with a peak in June, then disappearing in August. Tabanus nemoralis started to appear in April with a peak in May and disappearance after July. Dasyrhamphis algirus, Tabanus bromius, and Tabanus eggeri started to appear in May. Both Tabanus eggeri and Dasyrhamphis algirus peaked in June and July, whereas T. eggeri lasted until the end of September. Tabanus tinctus was observed in June with a peak in August and lasted until September.
