Myrmica ruginodis

Myrmica ruginodis is a species of ant that lives in northern parts of Europe and Asia. It is very similar to M. rubra, but has a more northerly and higher-altitude distribution. Overwintering larvae may become either workers or queen ants, with up to 20 queens living in a colony of up to 2,500 individuals. Two subspecies are recognised, differing in the relative size of the queen.
