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. This species is host to the social parasite Myrmica nefaria. (Radchenko and Elmes, 2010; Bharti, 2012)

In the Northwest Himalaya, the species was collected under the stones in subtemperate forests of scattered Cedrus, oak and some broad-leaved trees. Few collection sites were under intense anthropogenic activities, surrounded by apple orchards. The mean temperature and humidity recorded at the nest was 31°C and 63% respectively. The temperature ranges in summer (March to June) from 8°C to 36°C and during winter (November to February) from 3°C to 27°C. In Northeast Himalaya, nests were observed under stone in grasslands and on ground covered with dense vegetation, mostly in wet soil. Nesting sites had an average temperature of 15°C and relative humidity of 85%. Alates were collected during the months of June to early August in Northwest Himalaya, and in September to October in Northeast Himalaya. Altitudinal range of this species varies from 1341m at the Ekra peak to 4084m in Central Himalaya. (Bharti et al., 2016)

Identification

Radchenko and Elmes (2010) - A member of the rugosa complex of the rugosa species group. 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.

Description

Etymology

Radchenko and Elmes (2010) - name from the Latin word rupes = rock with the adjectival suffix estris = origin or habit, probably to indicate that it was found under a rock or in a rocky place.
