Although Crematogaster ants are always present, they do not appear to attend the larvae.
Some ants, like Crematogaster scutellaris, rob nectar without pollinating the flowers.
Adults have been recorded attending arboreal nests of Crematogaster ants.
Macaranga species often form symbioses with ant (Formicidae) species (particularly Crematogaster ants of the subgenus Decacrema) because they have hollow stems that can serve as nesting space and occasionally provide nectar.
The larvae are associated with an ant species of the Crematogaster genus.
Ants performing this activity include species in genera such as Camponotus, Pheidole, Crematogaster, and Pseudomyrmex.
The eggs are laid by the females of the species in stubs on Grey Mangrove trees where there is a presence of Crematogaster ant colonies.
