Ficus tinctoria var gibbosa: ant domatia

ABOVE: Ficus tinctoria var gibbosa  (male)  fig fruit. These ants appear to have hollowed out this ripe male fig fruit either so that they can use it for housing (domatia) or possibly also to use it for farming aphids.  If you look inside the red circle,  you will note two tiny almost transparent aphids, which must have been transported there by the ants.   Many species of ants “farm” aphids so that they can feed on on honey dew (sugary secretions) excreted by the aphids.

TOP: Male fig fruit in cross section. LEFT:  Cross section of male fig fruit inhabited by ants. RIGHT: Male ripe fig fruit. The ants were entering the male fig fruits via the open ostiole. Only a few figs were inhabited by ants.
The majority of fig fruits were not inhabited by ants.
