Habitat
Associated with Ficus trees; native range covers Australian and New Guinean where section Malvanthera figs occur. Some have been introduced to Mediterranean urban through ornamental plantings of Australian Ficus species.
Distribution
Native to Australia and New Guinea; one (P. claviger) recorded from Java. At least one species (P. imperialis) has been introduced to Greece and Cyprus, with established in urban environments where figs have been planted.
Host Associations
- Ficus section Malvanthera (subgenus Urostigma) - obligate mutualism; develop within figs and pollinate flowers
Life Cycle
Develops within figs of Ficus ; stages occur entirely within the enclosed fig syconium environment.
Behavior
Pollinating within figs. P. imperialis has been observed exhibiting host-switching in introduced range, developing in figs of Ficus watkinsiana in Greece—a host normally pollinated by P. nigriventris in Australia.
Ecological Role
Pollination mutualist for Ficus section Malvanthera; enables of fig . Potential role in supporting frugivore through fig production.
Human Relevance
Introduced associated with ornamental Ficus plantings in Mediterranean urban areas; monitoring recommended to prevent potential establishment in natural . No negative economic or environmental impacts documented to date.
