Very rare. - Range: Central and South Europe, Portugal to Ukraine and Morocco to Poland. Biology. This species lives in small colonies of 30-50 individuals under bark or in dead wood of old trees up to 2 m or more above ground in open deciduous woodland or parkland. Workers forage singly and are fugitive. Alatae have been recorded in early summer, May and June. Published as part of Collingwood, C.
