 They are primarily pollinated by various oligolectic native bees (e.g., "Centris", "Epicharis", and "Tetrapedia") that are specialized to collect floral oils, as the flowers do not offer the typical floral rewards.The fruits of serrette trees are important in the diets of certain wildlife, such as the golden conure ("Guaruba guarouba"), while the leaves of "Byrsonima" are food for some of the curious American moth-butterflies (Hedylidae).Plantings of "B. crassifolia" in the dry savannas of Oaxaca may even be suitable as substitute habitat for the Tehuantepec jackrabbit ("Lepus flavigularis"), an endangered species presently only found in three small relict populations.
