What kind of insect is horsefly?

The most numerous gadflies in the taiga zone, forest-steppe and forest. In the arid regions they inhabit along the banks of rivers and lakes, in the mountainous regions - right up to the zone of eternal snow.
Only females drink animal and human blood, while males feed on the nectar of plants. In appearance, they are smaller than females and have contiguous faceted eyes, whereas in females the eyes are separated by a chitinous strip. Females have a proboscis, which is equipped with a cutting apparatus. At the time of the bite of horsefly, the person feels severe pain.

Adult individuals of gadfly are born with a supply of all necessary substances and do not feed during life. They do not bite animals and humans, but females lay eggs on their hair or inject larvae into the animal's nostrils. Further, the larvae lead a parasitic way of life up to the transformation into an adult. The most significant in terms of damage are subcutaneous, nasopharyngeal and gastric gadflies that parasitize on horses, deer, cattle and camels. Cases have been described when the larvae of subcutaneous gadflies developed in humans, but this is rather the exception to the rule.
