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.

Of the 3 cities where we can rate Stinking Longicorn sightings, Melbourne ranks 3rd at under 5%. The best odds are in Perth (Australia, about 10%) and Sydney (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Stinking Longicorn is recorded against all the insects logged in Melbourne (27 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.
