Lasius is a genus of formicine ants comprising approximately 100 species distributed across the Holarctic region. The genus exhibits remarkable ecological diversity, including free-living species, temporary social parasites, and the hyper-social parasite Lasius fuliginosus. Many species are known as "citronella ants" due to their production of citronellal, a lemon-scented defensive compound. Lasius species are significant ecosystem engineers that modify soil properties and engage in mutualistic relationships with root-feeding aphids, herding them for honeydew production.
