Biology. This is an interesting species somewhat resembling a large paler M. lobicornisHNS but distinguished by the lower more cubical postpetiole. According to the Danish myrmecologist Chr. Skott, this species differs from other European MyrmicaHNS in having no winter brood, is mainly nocturnal and derives much of its food from the glandular excretions of low herbage such as Hypochaeris and Hieracium spp. The entrance to the nest is frequently built up as a collar of vegetable detritus (Bisgaard, 1944). Colonies are single queened and isolated, situated in sandy banks and dry pasture. Alatae are found in August, mating occurring on the ground near the nest.
