Ceratosolen fusciceps is a pollinating fig wasps which  are gall-makers (膽囊製造者).

Pollinating fig wasps either make their own galls or usurp 侵佔 the galls of other fig wasps

Flower ovules that receive an wasp egg become galled and the larvae consume the gall tissue.  The adult offspring emerge from the gall and mate inside the  fig fruit, before the winged female wasps disperse, carrying the flower pollen with them.

Pollinated flowers missed by the wasps (not galled) produce one seed each.
