ABOVE: Ficus treubii male fig fruits. From the open ostioles, the large size and the pale colour you can tell that there are 8 ripe male figs fin the photo above. The fig wasps have recently hatched and left via the ostiole. There is also one almost ripe green fig with closed ostiole (lower left). In dioecious figs including Ficus treubii the male figs act as brood chambers for pollinating fig wasps and do not produce seeds. Male figs are rarely eaten by animals and the fleshy parts probably contain a toxin to deter animals from eating them and thereby destroying the fig wasps.
