The known elevation range of this species in Hong Kong is from 29 to 475 m. A colony of S. minutula including three dealate queens, 47 workers, 97 pupae, and 80 larvae were collected in a log at Tai Po Kau on May 18, 2016. The presence of multiple queens and the high number of pupae and larvae retrieved indicate that functional polygyny and large colony size (300 individuals) as previously reported occur within this species ( Terayama et al. 2014 ). A single alate gyne was collected between June 26 and July 10 in a Malaise trap located within a mangrove area.
