This was confirmed in a genetic study done in 2017, which subsumed all the specimens into the species E. francisci which was placed outside all extant horse species in the new genus Haringtonhippus [19], although its placement as a separate genus was subsequently questioned. [20] A separate genus of horse, Hippidion existed in South America. [21]
Adult horse flies can be found in July and August. Males of this species feed on plant juices, while female are bloodsuckers. The females have a high fecundity. They can lay about 500 eggs at an oviposition. The larvae pass through 10–13 instars and the full life-cycle lasts 3–5 years. This horsefly may cause appreciable damages on stock farms.
Haringtonhippus is named after Charles Richard Harington. [3] It was originally described as a new Equus species, E. francisci, in 1915. [1] Dalquest (1979) considered Equus tau Owen, 1869, described from teeth in Mexico, a senior synonym of E. francisci, [7] while Equus quinni and E. arrelanoi were synonymized with E. francisci by Winans (1989).

Skeleton from the La Brea tar pits. Equus occidentalis (commonly known as the western horse) is an extinct species of wild horse that once inhabited North America, specifically the Southwestern United States, during the Pleistocene epoch.
Pangoniinae is a subfamily of horse-flies in the order Diptera, containing at seven tribes and over 40 genera. [2] [3] Insects in this subfamily are distinguished from other Tabanidae by possession of ocelli and the antennal flagellum usually has eight rings. [4]
Nannippus is an extinct genus of three-toed horse endemic to North America during the Miocene through Pleistocene, about 13.3—1.8 million years ago (Mya), living around 11.5 million years. [ 1 ] [ 2 ] [ 3 ] This ancient species of three-toed horse grew up to 3.5 feet (1.1 meters) and weighed between 165 pounds to 199 pounds, which was around ...
