Pison spinolae is a solitary wasp of the family Crabronidae, native to Australia and New Zealand. Like all insects, P. spinolae has a hard exoskeleton, one pair of antennae and three pairs of legs. These legs are strong as they need to be able to carry spiders back to their nests for their young. It has a segmented body divided into three sections; head, thorax and abdomen and two pairs of wings. An easily identifiable feature of the mason wasp, similar to other wasp species is the thin waist between the thorax and abdomen. This helps to tell the difference between a wasp and bee.

The nest of the mason wasp is constructed from predominantly sand and mud. It is small in size and widely abundant, found in places such as cracks of buildings and keyholes. The most obvious characteristic used for identification is... Wikipedia →

With luck
About 10% of wildlife watchers report a New Zealand Mason Wasp sighting in Arthur's Pass National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 60 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the New Zealand Mason Wasp is recorded against all the insects logged in Arthur's Pass National Park (11 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.
