Tetragonula carbonaria (previously known as Trigona carbonaria) is a stingless bee, endemic to the north-east coast of Australia. Its common name is Sugarbag bee. The bee is known to pollinate the orchids Dendrobium lichenastrum, D. toressae, and D. speciosum. It has been identified as an insect that collects pollen from the cycad, Cycas media. They are known for their small body size, reduced wing venation, as well as a highly developed social structure compared to honey bees.T. carbonaria forms honeycombs in their nests. The bee produces a consumable honey where the whole nest is sometimes eaten by Indigenous Australians. The bees ""mummify"" invasive small hive beetles (Aethina tumida) that enter the nest by coating and immobilizing the invader in wax, resin and mud or dirt from the nest.
