Pleistodontes froggatti
Mayr, 1906
Moreton Bay fig wasp
Pleistodontes froggatti is a small native to Australia with an obligate mutualistic relationship with the Moreton Bay fig (Ficus macrophylla). The was deliberately introduced to Hawaii in 1921 to support fig , and established in New Zealand by 1993 through long-distance or accidental transport. females are approximately 3 mm in length, while males are smaller at 1.5 mm and exhibit distinct coloration. The cannot reproduce outside the syconia of its specific fig.

Identification
Distinguished from other Pleistodontes by association with Ficus macrophylla ; females identified by 3.0–3.4 mm length with black-brown-reddish brown coloration, males by 1.5 mm length with yellow-orange bodies. Specific identification requires examination of morphological features not detailed in available sources.

Habitat
Associated with the syconia (fig fruits) of Ficus macrophylla; occurs wherever trees grow, including natural forests, urban plantings, and cultivated landscapes.
Distribution
Native to Australia: southeast Queensland, eastern New South Wales, and Lord Howe Island. Introduced to Hawaii (deliberately, 1921; recorded from Hawaiʻi, Lānaʻi, Kauaʻi, Oʻahu, Molokaʻi, and Midway Atoll; presumed on Maui). Established in New Zealand (first recorded 1993, now widespread).
Host Associations
- Ficus macrophylla - obligate mutualismExclusive ; pollinates fig and reproduces only within its syconia
Life Cycle
occurs exclusively within the syconia of Ficus macrophylla. females live 2–3 days. Specific details of , larval, and pupal stages not documented in available sources.
Behavior
females disperse to locate receptive fig syconia; long-distance has been observed across 3,000 km of open ocean to New Zealand. Dispersal likely aided by air currents; hitchhiking on aircraft also possible.
Ecological Role
Obligate of Ficus macrophylla; mutualism enables fig and seed production. In New Zealand, arrival led to prolific fruit production with small seeds adapted for bird , potentially altering local dynamics.
Human Relevance
Deliberately introduced to Hawaii in 1921 by Maui Pineapple Company to support Ficus macrophylla . Spread in New Zealand facilitated by widespread urban planting of figs. No documented negative economic or health impacts.

Etymology
Specific epithet 'froggatti' honors Australian entomologist Walter Wilson Froggatt, who provided the first biological account of the in 1901.
Dispersal capacity
Long-distance of New Zealand (3,000 km from Australia) demonstrates exceptional ability; meteorological analysis indicates approximately 21 days per year with favorable wind conditions for 1–3 day crossing.
