A Camponotus (Myrmmobrachys) ant feeds from the nectaries of an Inga plant. The plant presumably gains protection from herbivorous insects by attracting ants in this manner.

A cluster of epiphytic Myrmecodia ant-plants in an Australian woodland.  The swollen base of Myrmecodia is hollow, with an intricate gallery of chambers that house aggressive Philidris ants.  The ants defend the plant and provide the plant with nutrients.

The ants defend the plant (not very effectively in this case, judging from the holes in the leaves), and provide the plant with nutrients.
