Pollination
The bee species Trigona spinipes is an effective pollinator of Nymphaea pulchella. In some cases, the bees coated in pollen fall into the stigmatic fluid and die.[6][3] The flowers are also visited by the bee species Apis mellifera, as well as flies.[3]
Herbivory
The bee species Trigona spinipes is florivorous, i.e. it consumes parts of the flowers of Nymphaea pulchella.[6]
