Zorion guttigerum, commonly known as the Flower longhorn beetle, is an endemic species of beetle in New Zealand. It is found on the flowers of many plant species and feeds on nectar and pollen. Zorion guttigerum was first described as Obrium guttigerum by John Westwood in 1845, and was later reassigned to genus Zorion.
Zorion currently includes 10 extant species, all of which are endemic to New Zealand. They belong to the family of longhorn beetles (Cerambycidae), of which there are approximately 180 known endemic species. In New Zealand, long-horn beetles are important pollinators for native plants, including harakeke (common flax).
Zorion guttigerum is widespread throughout the North Island and South Island. Adults are variable in size and can range from 3–7 mm in length. They are a dark purple brown colour with a bright golden spot on each elytron. They have been described as the most strikingly colourful beetle within New Zealand fauna. Unlike most Cerambycinae species, where the antennae are elongate and extend past the body, Z. guttigerum have antennae generally shorter than their body. Males tend to have longer antennae...

Rare
Under 5% of wildlife watchers report a Zorion guttigerum sighting in Auckland on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 459th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October and November
In those months about 10% of wildlife watchers report a Zorion guttigerum in Auckland on a given day, against under 5% in December to September, the lowest months.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Zorion guttigerum sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Zorion guttigerum is recorded against all the insects logged in Auckland (9 verified sightings), 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.
