The Polyrhachis hookeri, often known as the “Green Spiny Ant,” is Australia’s shimmering answer to the “blue” species found in the Philippines. While it is smaller than some of its giant cousins, it makes up for its size with incredible iridescence. Depending on the angle of the light, their bodies can shift from a deep, forest green to metallic hues of gold, blue, or even purple. They are a “shy” species of the Australian woodlands that offer a much more manageable experience for keepers who want a stunning, colorful ant without the expert level stress.
