Yellow Shadow Ant

Lasius umbratus, colloquially known as the yellow shadow ant and yellow lawn ant, is a Palearctic species of parasitic ant distributed across Eurasia and the Maghreb region of Africa. It was once thought that this species occurred in North America as well, but comparative genomic studies indicate the Afro-Eurasian and American populations are discrete and not closely related enough to represent a single species. The North American populations are now treated as a different species, Lasius aphidicola.
