Ecology
A survey conducted in Hong Kong observed fruit bats feeding on the seed figs of F. fistulosa and two other species in the subgenus Sycomorus, namely F. hispida and F. variegata. Most of the bats were identified as Cynopterus sphinx, while the larger individuals were thought to be Rousettus leschenaultii, the only other fruit bat species in Hong Kong.
