Another fly from my upcoming set... Horse flies are found all over the world except for some islands and the polar regions (Hawaii, Greenland, Iceland). This specific species of horse-fly is present in most of Europe, in the Near East, and in the eastern Palearctic realm. It mainly lies in heath and moorland, and in spruce forest edge. It is also known as the notch-horned cleg fly, or simply “cleg” in Scotland and northern parts of Ireland. They can be encountered during the daylight hours from late May through late October. The males are harmless and feed on nectar, while the females feed on mammal blood. They feed mainly on cattle and horses, needing blood for developing eggs (hence the Latin and Common name). They can also bite humans, which can be very painful.
