Abstract
The resources utilized by Centris flavofasciata were studied near Mexico's Pacific coast. An analysis of pollen showed that these bees are polylectic.Sixteen pollen types were found, belonging to eight plant families; however only three plant species (Lonchocarpus guatemalensis, Tabebuia rosea, Prockia crucis) were found in abundance. The plant families that occurred most in pollen samples were Leguminosae, Bignoniaceae and Flacourtiaceae. The Leguminosae was rich in species and was an important pollen resource for the bees investigated.Centris flavofasciata forage less resources than other Centris species and no plant family was represented by >70% the counted grains.
