A member of the lobicornis complex of the lobicornis species group. Radchenko and Elmes (2010) - In Europe the main characters used to separate its species from the schencki-group species are the shape and size of the lobes on the bend of the antennal scape, combined with the relative frons width (FI). However, in Europe these features can be very variable between local populations and can overlap those of schencki-group species.
Collingwood (1979) - Bicoloured reddish brown with head and gaster characteristically darker. Upright tooth-like process at the bend of the antennal scape, frequently very large in Scandinavian samples but very variable in size over its whole geographic range. Frons about 1/3 head width. Petiole high with anterior and dorsal surfaces meeting at a right angle. Postpetiole broadly oval from above. Head Index: 87.8; Frons Index: 30.8; Frontal Laminae Index: 65.5. Length: 4.0-5.0 mm.

Radchenko and Elmes (2010) - Boreo-montain species. North Europe, northern part of Central Europe, British Isles, mountains of Central and Southern Europe (in Iberian Peninsula is absent), Forest Zone of East Europe, Caucasus, West Siberia and NE Kazakhstan (to the south till Saur Range), East Siberia (to the east till Transbaikalia), Mongolia. Records for Russian Far East and China (Eidmann 1941; Kupyanskaya 1985; Wei C. et al. 2001) almost certainly belong to other species.

Radchenko and Elmes (2010) - Despite being an "old" and well-known species in Europe, the ecology of M. lobicornis has not been well studied. It has been used as a model species in chemical studies of glandular secretions in a team led by Prof. David Morgan, its role as a host for Phengaris butterflies has been investigated recently, and Prof. Vladilen Kipyatkov has made some observations on physiological response to seasonality. The most probable reason for this is that over most of its entire distribution this species is common in the sense that one can occasionally find the odd colony living in more or less any biotope, but unlike most other widely distributed Myrmica species it almost never dominates any particular habitat-type anywhere in its range and in this sense can be considered rare. It is more common in boreal habitats and we found it to be relatively abundant in some pine forests of northern Finland. In most northern habitats, the narrow-frons form (M. lobicornis “S. str.”) tends to be a quite cryptic-foraging species; in subarctic conditions we have observed quite small individuals foraging on the soil surface under the moss layer that might initially be mistaken for Leptothorax species. Even in southern England it is quite hard to observe foraging workers.
Generally colonies are small (< 200 workers) with at most 2 queens, however in Central Lapland, Finland we found one very large colony (probably> 2,000 workers) that had made a large earth solarium in grass on the bank of a small stream in a forest, but we could find no queens in this nest. Its greater abundance in Finland led to the only genetical study of M. lobicornis (Seppa 1994), who showed that on one study site in Finland most colonies averaged about 300 workers but rarely exceyd 500 workers and were monogynous (or queenless), on average queens live about two years and regular replacement of queens by queenless colonies was inferred.
In Finland M. lobicornis is not usually found in dense old forest, Myrmica ruginodis is usually the only Myrmica species found in such (> 100 years) forest (Punttila et al. 1991). M. lobicornis and the other two common forest Myrmica species, Myrmica scabrinodis and Myrmica sulcinodis, are found in regenerating forest but none of these can be considered as primary colonising species like M. ruginodis, nests of which persist after clear felling and rapidly expand into the new habitat. Nests of M. lobicornis and the other two species must be established by queens flying into the felled areas. Punttila et al. (1991) showed that this occured sometime after two years and that by 110 years after forest clearance the population of M. lobicornis was well established, though individual workers were much less abundant than those of the other three species. Numbers decline as the new forest closes over but it is not known how long M. lobicornis colonies persist in mature forest in Finland. In the much warmer ancient mixed (mostly pine and some deciduous) woodland near Kiev, Ukraine we have observed colonies of up to seven Myrmica species, including M. lobicornis. However the dominant species are Myrmica rubra and M. ruginodis and the other Myrmica species are relatively rare.
In the glades of the Tatry mountains of southern Poland M. lobicornis were present at only 7 of 23 studied sites compared with 20 and 13 sites for M. ruginodis and M. scabrinodis respectively; when present, nests of M. lobicornis averaged 13% of the population of all ant nests compared to 52% and 19% respectively for the other species (Woyciechowski, 1990c). On the meadows on the southern slopes of a mountain in the Beskid range of southern Poland, M. lobicornis nests comprised only 6% of the population of ant nests despite being the third most abundant species after M. scabrinodis (30%) and Lasius flavus F. (57%) (Woyciechowski and Miszta 1976). Nuptial flights have been observed from the end of July to mid September, and M. lobicornis males often join swarms dominated by other Myrmica species.
Collingwood (1979) - It is a mountain species in Central and S. Europe but in the north occurs equally on lowland heath and in open woodland. Although widely distributed it is not abundant and occurs in isolated single queen colonies nesting in peat or under stones. It is commonly found as single foraging workers and is one of the least aggressive members of the genus.
