Centris hoffmanseggiae

North America; Middle America. Distribution records indicate presence in both regions, though specific countries or localities are not well documented in available sources.

Female bees collect fatty oils from floral elaiophores, mixing these oils with pollen to provision larvae. This oil-collecting behavior is characteristic of the genus Centris.

• Krameria - pollinatorKrameria species produce fatty oils instead of nectar; female Centris bees collect these oils from elaiophores on the flowers, pollinating the plant in the process. The relationship is not mutually exclusive—Centris bees use multiple oil-producing plants.

Female bees have been observed visiting flowers at ground level, producing a distinctive buzz while moving between blooms. This buzzing likely facilitates oil collection from floral structures.

Pollinator of oil-producing plants, particularly Krameria species. The bee's foraging activity is essential for Krameria reproduction, as these plants depend entirely on Centris bees for pollination.

• Centris lanosaBoth species are oil-collecting bees in the same genus that visit Krameria flowers; C. lanosa was specifically noted from Krameria lanceolata in Oklahoma, suggesting potential overlap in host use and habitat with C. hoffmanseggiae
