Extrafloral nectar provision during floral ontogeny in ant‐plants has not been widely studied. Extrafloral nectar secretion differed between leaves associated with buds, flowers, and fruits, and peaked during anthesis when pollinators were present. This ontogenetic variation may result from mixed selective pressures involving strategies for defense and mutualist management.
