The genus consists of around 200 known species and additional subspecies,[2] although this figure is likely to rise as soon as the Chinese and
Nearctic fauna lists are revised.[4][5]
Inquilines
The genus contains a number of
inquiline species (commensal symbionts), other Myrmica species that manage to invade the nest of their host. Subsequently, they use hormones to manipulate the host colony in such a way that eggs of the host queen develop into workers, and parasite brood into sexuals. Hence, the parasite is not able to sustain a colony of its own, but uses host resources instead.[6][7]
Similarly, larvae of the butterfly genus Maculinea (a junior synonym of Phengaris, family
Lycaenidae) and of the
southern armyworm, live inside Myrmica nests where they are either directly fed by ants or prey upon ant brood. This parasitism is employed primarily by specific species such as Phengaris arion forming predatory relationships.[8]
