Description: Polyrhachis phryne are known as spiny ants due to the spikes coming off of their lower thorax. They're a beautiful species but are rather timid and shy while young. They show the most activity during the night making them nocturnal. More of an arboreal species but will do well in most setups and are often kept in Y-Tong nests. Very easy to keep and contain due to their manageable mature colony size. Hardy exotic species.
