Rare
Under 5% of wildlife watchers report a Steirastoma stellio sighting in Buenos Aires on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 425th most-seen of the 558 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Steirastoma stellio in Buenos Aires on a given day, so our monthly data shows no clear season.
Only Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Steirastoma stellio sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae

GBIF citizen-science records
It is estimated from how often the Steirastoma stellio is recorded against all the insects logged in Buenos Aires (8 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.
