|Hybomitra montana. Ventral view|
Hybomitra montana can reach a length of 12.5–16 millimetres (0.49–0.63 in). The body is black, the hairy abdomen is yellow with black stripes and the wings are brownish but transparent. The compound eyes are well developed in both sexes. They have bright blue-green eyes, with transversal red bands.
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.
These horseflies live in various open landscapes, from mountanins to peatlands and salt marshes.
