Certonotus fractinervis is New Zealand's largest native wasp and it is one of two species of Labeninae in New Zealand. It is a parasitic wasp that parasitizes Rhynchodes ursus. Certonotus fractinervis is a slender, long ichneumon wasp. Certonotus fractinervis is a part of the subfamily Labeninae. A closely related species of the Labeninae family is suggested to be Poecilocryptus zealandicus. Species in the Labeninae family can be identified from other Ichneumonidae because they have their metasoma, the posterior part of the body, located high on the propodeum, the first abdominal segment. Certonotus fractinervis has a larger body size than P. zealandicus. The female has a body length of 27 millimeters, forewing length of 20 millimeters, antennae length of 19 millimeters, and a long ovipositor with a length of 35 millimeters. Certonotus fractinervis can be distinguished by the bright yellow spots that go down the center of the metasoma as well as the apical white ends of the antennae, about a third of the way up. The head of the insect is yellow with two parallel streaks of brown from the base of the antennae to the clypeus. The clypeus, the broad plate of the insect... Wikipedia →

With luck
About 10% of wildlife watchers report a Certonotus fractinervis sighting in Fiordland National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 201 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Certonotus fractinervis in Fiordland National Park on a given day, against under 5% in April to December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Certonotus fractinervis sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate Certonotus fractinervis sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Hymenoptera
The closest relatives of the Certonotus fractinervis that you can see in Fiordland National Park (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Buff-Tailed Bumble Bee (about 20%), Common European Yellowjacket (about 10%) and New Zealand Mason Wasp (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Certonotus fractinervis is recorded against all the insects logged in Fiordland National Park (9 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.
