Nectar robbers vary greatly in species diversity and include species of carpenter bees, bumblebees, stingless Trigona bees, solitary bees, wasps, ants, hummingbirds, and some passerine birds, including flowerpiercers. [1] Nectar-robbing mammals include the fruit bat [2] and Swinhoe's striped squirrel, which rob nectar from the ginger plant. [3]
They are among the largest bees found in California and Hawaii, [12] growing to around 1 inch (2.5 cm) in length. Smith's original description was: Female.—Black; head and thorax closely and moderately punctured; the mesothorax smooth, impunctate and shining on the disk; metathorax rounded behind; abdomen shining rather finely punctured, most closely so at the sides above; the pubescence ...
However many carpenter bees "rob" nectar by slitting the sides of flowers with deep corollae. Xylocopa virginica is one example of a species with such nectar robbing behavior. With their short labia the bees cannot reach the nectar without piercing the long-tubed flowers; they miss contact with the anthers and perform no pollination.

As with other carpenter bees, the larvae are fed a mixture of pollen and nectar. The females have a mutualistic association with phoretic mites that are transported from nest to nest in an abdominal chamber, called the acarinarium. [2] [3] The mites feed on nest fungi that may otherwise infest the nectar and pollen provisions of the larvae. [2]
