Hairy Wood Ant
Formica lugubris
- Near threatened
- Card rarity: Uncommon
- Insects

Formica lugubris, also known as the hairy wood ant, is commonly found in wooded upland areas across northern Eurasia. Colonies construct large thatched mound nests occupied by thousands of workers, and one or more queens. Workers look similar to other species of wood ants, but Formica lugubris workers can be identified by a fringe of hairs that reaches down to their eyes and prominent hairs between the facets of their compound eyes. Workers can reach sizes of up to 9 mm long; queens are larger, reaching 12 mm long.
