Pollination and dispersal of the sapucaia.

On the left: flowers of the sapucaia (Lecythis pisonis) being visited by female carpenter bees (Xylocopa frontalis). The bees collect sterile pollen from the anthers in the androecial hood for feeding the colony's larvae. During the visit, fertile pollen from the anthers of the staminal ring is deposited on the heads and backs of the bees. This pollen is subquently rubbed off onto the stigmas of subsequent flowers visited in other trees, thereby effecting cross-pollination. On the right:  fruits of the sapucaia​ being visited by the greater spear-nosed bat (Phyllostomus hastatus). The bats carry away the seeds to their night roosts where they eat the white aril at the base of the seeds. Seeds that drop under the roost or while being carried away from the tree are. thus, dispersed by the bats.
