Macrosaldula scotica is a predatory species of true bug, from the family Saldidae in the order Hemiptera from the western Palearctic.

The first segment in the antenna and the lower and middle part of the femora have longitudinal black and white stripes.

[5] Macrosaldula scotica is usually recorded running over rocks and boulders along the margins of upland and mountain streams.

[2] Like other Saldidae Macrosaldula scotica is a very active predator of smaller insects and other arthropods, very agile on the ground and making jumping flights.

The adults are active and readily take flight, although they will hide among pebbles on cloudy days.
