Exoneura hackeri

The species occurs in eastern Queensland. Type localities include Sunnybank in Brisbane, and Stradbroke Island.^[2]

The adults are flying mellivores with sedentary larvae. They nest in the dead, dry stems of plants on rainforest margins. Two or more adult females may occupy one nest, though not all females lay eggs. All the immature stages may be found in the communal chamber, with the larvae fed progressively. Flowering plants visited by the bees include Hibbertia and Leptospermum species.^[2]
