Centris hoffmanseggiae
Centris hoffmanseggiae is a centridine bee in the family Apidae. It is known to occur in North America and Middle America. Like other members of the genus Centris, it is an oil-collecting bee that gathers floral oils from specialized plant structures. The species was described by Cockerell in 1897.
Centris lanosa
Wooly Oil-Digger
Centris lanosa is a specialized oil-collecting bee in the family Apidae, commonly known as the wooly oil-digger. It is one of the few bee species that has evolved to collect fatty oils rather than nectar from flowers, specifically from Krameria species. The bee mixes these oils with pollen to provision its larvae. It has a disjunct distribution across the southeastern and southwestern United States, with populations separated by more than 250 km.
Centris rhodopus
red-legged centris, Red-legged Oil-Digger
Centris rhodopus is a species of oil-collecting bee in the tribe Centridini, family Apidae. It is distributed across Central America and North America. Like other Centris species, it has been observed collecting floral oils from specialized oil-producing flowers, particularly in the genus Krameria. The species is part of a group of bees adapted to harvesting non-nectar floral rewards.
