| Hippobosca equina|
Hippobosca equina, or the Forest fly, is a fly from the family Hippoboscidae. They are blood-feeding ectoparasites of horses, and sometimes cattle.. It is a permanently fully winged fly, not shedding its wings on finding its host, as in some other Hippoboscidae. this means it may leave its host to deposit its larvae. They are good fliers.
Wing length 6-8.5mm..
The primary distribution is in Europe and Parts of Asia and Africa. It has been introduced to other locations, though in some cases latter eradicated by modern husbandry practices. . In the UK they are know primarily from the New Forest and increasingly from South Devon. There are occasionally recorded from other part of the UK, though some reports as far north as the Scottish borders are considered dubious.In the UK their flight period is from May to October, but peaking August and early September. 
The primary host are equines, they are ofter also frequently found on cattle on which they are able to maintain a population. They have been know to bite a number of other mammals, including sheep, goats, and sometimes humans, Other mammals it may also live on are Red Deer, Camel, Rabbit and on birds, the Grey Heron, and the Northern Goshawk. They have been feed and bred on Guinea pigs in the laboratory.
