Polyrhacis is known as the spiny ant to many people and are very popular to keep in the AntKeeping community.  Queens are 14-16mm silver / black /gold specs whilst workers are 10-12mm.

They do appreciate temperatures of 28-30c as they actually thermoregulate themselves, with cooler temperatures even at 24c you’ll notice decreased activity and feeding so it’s advised to keep their temps up.
