Ant ID:Acro.oct

Acromyrmex octospinosus, commonly known as Leafcutting Ants. They are the most well known species of the Acromyrmex genus. They cultivate a fungus of species: Leucoagaricus gongylophorus which produces fruiting bodies for the ants to eat. The ants do not eat the leaves, but instead feed them to the fungus which releases digestive enzymes to break down the pulped leaf/plant material in order to grow. The fungus and the ants share a symbiotic relationship in which one could not survive without the other. Acromyrmex octospinosus are a polygyne species meaning they can have many Queens in a single colony

An Acromyrmex octospinosus colony can reach 40,000 individual ants, less than the Atta genus therefore a large enclosure is required with lots of space for expansion and suitable escape prevention is necessary, in the form of a moat. There are many castes of workers in an Acromyrmex octopsinosus colony: Minima, Minor, Media, Major. Each different caste performs a different job, for example the tiny Minima workers pulpifying the plant material for digestion by the fungus.

Description of Queen:12-14mm Orange to Brown

Description of Workers:5-15mm Dark Brown
