Stenoderus suturalis, commonly known as the stinking longicorn, is a species of longhorn beetle found in southern parts of Australia, including Western Australia. Growing to about 20 mm, the legs, head and thorax are glossy black. The elytra is a coloured orange.
When threatened, the stinking longicorn will release a stinking fluid from glands near the eyes, located laterally near the mandibular articulations. Wikipedia →

About 10% of wildlife watchers report a Stinking Longicorn sighting in Perth on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 115th most-seen of the 275 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Stinking Longicorn is recorded against all the insects logged in Perth (19 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.
