Cuckoo Bees are parasites, in that the female cuckoo bee lays her eggs in the nest of other bees, primarily digger and mining bees. Cuckoos are also said to be kleptoparasites, stealing honey and pollen collected by others. Cuckoo bees lack any pollen-transporting apparatus. Look for cuckoo bees flying low over the ground and foliage, hunting for foraging and nesting potential victims.
There is also a family of cuckoo wasps which lay their eggs in the nests of potter and mud dauber wasps; many types of wasps in various families have evolved similar habits. These insects are normally referred to as "kleptoparasites," rather than "brood parasites." The distinction is that the term "brood parasite" is generally restricted to cases where the immature parasite is fed directly by the adult of the host, and raised as the host's offspring (as is common in cuckoo birds). Such cases are virtually unknown in bees and wasps, which tend to provide all of the food for the larva before the egg is laid; in only a few exceptional cases (such as parasitic bumblebees) will a bee or wasp female actively feed a larva that is not her own species. The difference is only in the nature of the interaction by which the transfer of resources occurs (tricking a host into handing over food rather than stealing it by force or stealth), which is why brood parasitism is considered a special form of kleptoparasitism. -- from Wikipedia
"Kleptoparasitism is an important means by which many animals obtain limited resources. The success of kleptoparasitism may be influenced by a number of factors, including competitive differences among individuals and the spatial distribution of prey and hosts."

This cuckoo bee was busy drinking nectar - this seems to be their preferred pose, with head buried in a flower.
|"Anthophorid Bees (920 NA spp) are most diverse in the western U.S. Three distinctive subfamilies are recognized: Nomadinae (Cuckoo Bees), Anthophorinae (Digger Bees), and Xylocopinae (Carpenter Bees). " |

belong to this large order, which also includes sawflies. Most species are solitary, but some, such as the domestic honeybee, exhibit a complex social structure in which exist sterile female workers and fertile male and female royalty.
