Inhabits mainly mountain forests (fir, spruce, larch, birch), at altitudes between 1000 and 2600 m, mostly around 1600-2000 m, but also bushes (mainly juniper), peat bogs, subalpine meadows and mountain tundra. In forests, it builds nests almost exclusively in rotten wood, but in open habitats the ants construct moss mounds and build nests in soil under stones or dead wood. Nuptial flight is in August. (Radchenko and Elmes 2010)
Radchenko and Elmes (2010) - A member of the kurokii group. This large and robust species is superficially similar to some rubra-group species (e .g. 'Myrmica ruginodis, Myrmica arisana, etc.), but well differs from them by having frontal carinae that do not curved outwards and do not merge with the rugae surrounding antennal socket, a short petiole with weakly developed peduncle, much denser rugulosity on the head dorsum and by having a densely punctated surface between rugulae.

Radchenko and Elmes (2010) - this species was obviously dedicated to a Mr. Kuroki but Forel did not say who he was. He might possibly have been a Japanese collaborator of the German collector and lepidopterist Hans Fruhstorfer who owned the material, or more probably he was the Japanese General Kuroki Tamemoto who in 1904-1905 had become famous for his part in the Russo-Japanese war.
