Messor concolor

The biology of this species is poorly known. Workers were collected at midday, in the dry riverbed located in Imbros Gorge. Area was overgrown by phrygana. Most probably, as in all Cretan Messor species, nest was located in soil (Salata & Bororiec, 2019). Pashaei Rad et al. (2018) found this species in Iran on parkland ground in a moderate rainfall area.
