Biology
Collingwood (1979) - This is a sluggish slow moving species; workers are often found individually in nests of other ant species and on disturbance tend to curl into a tight ball. Colonies occur under stones in stony pastures and in open woodland and may consist of several hundred workers with several queens and often including intermediate forms between worker and queen. This species is mainly scavenging and does not attend aphids. Alatae are developed during late summer and have been taken outside nests from August to October.
