The pollination ecology of the tropical shrub, Ardisia escallonioides (Myrsinaceae), was studied over a three year period 1992-94 at three subtropical hardwood forests in Dade County, Florida. The flowering phenology is a “pulsed regular annual” pattern with distinct seasonal fall flowering. Although flowers are protogynous, individual plants are hermaphroditic due to staggered flower opening within and among in- florescences. Twelve species of insect taxa visited flowers, with halictid bees the most numerous (94%). The most abundant insect was the halictid bee Augochlora pura mosieri, comprising 83% of all visits. Insect behavior on flowers was correlated with foraging techniques on the pollen-only reward flowers.
