These tiny, elongated Reed Bees, up to 8 mm long, are Australia's least known social bees! They escavate tiny nest burrows inside pithy stems of plants such as grass trees or tree ferns. Two or more adult bees may share a nest and co-operate to share the nest duties.
Reed Bees have a glossy black head and thorax. Their abdomen has a wedge shape (viewed from the side) and is either black or orange-red. Many Reed Bees also have a T-shaped cream mark on their face. Reed Bees belong to the genera Exoneura and Braunsapis.
