Myrmica rupestris

M. rupestris has been collected at relatively higher altitudes than Myrmica rugosa, between 2100 and 4100 m. Nests are built in soil, often under stones, in open deciduous and mixed forests, and places with steppe-like vegetation (Philip Ward, pers. comm.). Like M. rugosa, queens and males have been found in nests of M. rupestris from the end of May to the end of June, much earlier than in Euro-Siberian species.

Identification
Radchenko and Elmes (2010) - A member of the rugosa-group (see also Radchenko and Elmes 2001 b). It differs from most other members of this group, Myrmica rugosa, Myrmica aimonissabaudiae and Myrmica hecate, by the much coarser sculpture on its petiole and postpetiole; M. rupestris most resembles Myrmica foreliana, from which it differs by the lack of punctations on the surface of the head and alitrunk between rugae.

Distribution
