Lasius umbratus is a parasitic Formicinae. To gain access to the nest of the hosts (mostly Lasius niger) the Queen kills a worker ant to gain their scent. This will make it easier to infiltrate the host colony. However only a very small number of Queens are successful to access mostly small host colonies. After infiltration the host Queen will be neutralised either by killing or expelling. The host worker ants accept the new Queen and keep care on her brood. As there are more and more Lasius umbratus workers, the remaining host workers gets killed.
