Austroplatypus incompertus

Austroplatypus incompertus is a species of ambrosia beetle belonging to the weevil family, native to Australia, with a verified distribution in New South Wales and Victoria.[1] It forms colonies in the heartwood of Eucalyptus trees and is the first beetle to be recognized as a eusocial insect.[2][3] Austroplatypus incompertus is considered eusocial because groups contain a single fertilized female that is protected and taken care of by a small number of unfertilized females that also do much of the work.[4] These beetles appear to be the oldest farming creatures, having domesticated fungi nearly 90 million years ago.[5] The species likely passed on cultivated fungi to other weevils.[6]
