Messor structor is a species in the subfamily Myrmicinae. They are also called the harvester ant, because they are known to take various types of seeds and grind them into a paste which they then feed to the larvae and the queen. They are moderately easy going and are undemanding to their conditions making them an ideal genus for patient beginners. It is important that this species is in a place where there are little or no vibrations, this species is very sensitive to this and therefore gets stress.
