"Pleistodontes frogatti" is a small wasp. Females are 3.0–3.4 mm (0.12–0.13 in) long with black, brown and reddish brown bodies. Males are 1.5 mm (0.06 in) in length, with yellow and orange bodies.
Taxonomy
The specific epithet, "froggatti", is in honour of Australian entomologist W. W. Froggatt. The first account of the species' biology was written by Froggatt in 1901, who imperfectly identified it as "
Pleistodontes imperialis ". Austrian entomologistGustav Mayr re-described the species in 1906 and named it in honour of Froggatt.Reproduction
Figs have an obligate
mutualism withfig wasp s, (Agaonidae); figs are only pollinated by fig wasps, and fig wasps can only reproduce in fig flowers. "Pleistodontes frogatti" can only reproduce in the syconia of its host species, the Moreton Bay Fig, "Ficus macrophylla".Distribution
"Ficus macrophylla" is native to southeast
Queensland , northeastNew South Wales andLord Howe Island , and has been planted widely across the world. "Pleistodontes froggatti" has been found across most of the range of its host tree in Australia. It also occurs in New Zealand and Hawaii.The
Maui Pineapple Company introduced "F. macrophylla" to its lands in the 1920s. "P. froggatti" was introduced to Hawaii in 1921cite journal | quotes = no | last = Evenhuis | first = N.

It has also been collected in theMidway Atoll .cite journal | quotes = no | last = Beardsley | first = John W. | year = 1999 | title = Hymenoptera from Midway Atoll| journal = Bishop Museum Occasional Papers | volume = 58 | pages = 37–50 | url = http://hbs.bishopmuseum.org/pdf/beardsley99.pdf ]"Pleistodontes froggatti" was first recorded in New Zealand in 1993, a 3,000-km (1,900
mile ) journey from its nearest range in Australia. Adult female wasps usually live 2–3 days; there are, on average, 21 days over the course of a year during which it would be possible for make the trip in 1–3 days on air currents. In addition, a female wasp could hitch a ride on an aircraft. After establishing in New Zealand, "P. froggatti" spread rapidly, making use of widely planted populations of Moreton Bay figs. The arrival of the wasp led to prolific production of fruits containing many small seeds adapted for dispersal by birds.References
