Priocnemis monachus is a species of spider wasp endemic to New Zealand, where it is known as the black hunting wasp or ngaro wīwī. It hunts large tunnelweb or trapdoor spiders, paralysing them with its sting and storing them in burrows for its larvae to eat alive. It is the largest member of the family Pompilidae in New Zealand.
The holotype of this species was collected by Joseph Dalton Hooker, and is in the Banks collection of the British Museum of Natural History. It is one of a number of species named but not described by Adam White, and intended to appear in the series Voyage of the Erebus and Terror, but not in fact being published there. In error, Frederick Smith in 1855 attributed the species to White, but Smith's listing of it as Pompilus monachus in his Catalogue of hymenopterous insects in the British Museum is the first published description. In the years following its description, the species has been placed in the genera Pompilus, Salius, Trichocurgus, and Chirodamus, but in Anthony Harris's 1987 revision of New Zealand pompilids he assigned it to Priocnemis, subgenus Trichocurgus.

With luck
About 10% of wildlife watchers report a Priocnemis monachus sighting in Egmont National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 79th most-seen of the 191 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April, September and December
In those months about 20% of wildlife watchers report a Priocnemis monachus in Egmont National Park on a given day, against under 5% in January, May–August and October–November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Priocnemis monachus sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Priocnemis monachus sightings, Egmont National Park has the highest daily chance: about 10%. Next come Rakiura National Park (New Zealand, about 10%).
Same order: Hymenoptera
The closest relatives of the Priocnemis monachus that you can see in Egmont National Park (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Buff-Tailed Bumble Bee (about 10%), Asian Paper Wasp (about 10%) and Common European Yellowjacket (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Priocnemis monachus is recorded against all the insects logged in Egmont National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
