The [[Queen ant|queens]] of this species seek out a [[Black garden ant|''Lasius niger'']] [[worker ant]] to first kill in order to gain the worker ant's [[Pheromones|scent]] and then to discreetly sneak inside a ''L. niger'' nest. Once inside the ''L. umbratus'' queen finds the ''L. niger'' queen, and kills her. The worker ants will care for the new queen's larvae and slowly the colony will be made up of only ''L. umbratus'' individuals. Ant species like ''[[Lasius fuliginosus|L. fuliginosus]]'' find ''L. umbratus'' colonies and found their own nest by killing the ''L. umbratus'' queen.<ref>{{Cite web | url=http://www.bogleech.com/bio-insects.html |archive-url=https://web.archive.org/web/20080915202227/http://www.bogleech.com:80/bio-insects.html |archive-date=2008-09-15 |title = Insects and other Arthropods}}</ref> They have a Parasitic Nesting Behavior which means It is known to infiltrate and take over colonies of other ant species

They are sometimes confused with ''[[Yellow meadow ant|L. flavus]]'' (yellow meadow ant) but unlike ''L. flavus'' they forage for food on the surface.{{citation needed|date=February 2015}}
