Port Jackson Fig Wasp

Pleistodontes imperialis is a native to Australia that maintains an obligate mutualism with Ficus rubiginosa (Port Jackson fig), serving as its exclusive . It is the type of the Pleistodontes. The species has been introduced outside its native range through the ornamental planting of its figs in Mediterranean urban , with confirmed records from Greece and Cyprus. In its introduced range, it has demonstrated host-switching , also developing in Ficus watkinsiana figs despite this species having a different native pollinator.
