The tribe Euglossini, in the subfamily Apinae, commonly known as orchid bees or euglossine bees, are the only group of corbiculate bees whose non-parasitic members do not all possess eusocial behavior.

The pollen basket or corbicula is part of the tibia on the hind legs of the female of certain species of bees. They use the structure in harvesting pollen and carrying it to the nest or hive where it is used as food by the colony.
