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.
