ABSTRACT
Evidence is presented that the extrafloral nectaries (EFN) of Acacia longifolia Andr. Willd. serve as sources of rewards that attract pollinating insects. Bees and wasps feed at EFN often crawling over inflorescences and passively vectoring pollen as birds do on A. terminalis. The position in relation to inflorescences, timing of secretion in relation to flowering, and visitation behavior of pollinating insects support this hypothesis.
