Rare
Under 5% of wildlife watchers report a Mamerthes orionalis sighting in Buenos Aires on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 404th 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 Mamerthes orionalis in Buenos Aires on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Mamerthes orionalis sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Mamerthes orionalis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Mamerthes orionalis that you can see in Buenos Aires (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Ctenucha rubriceps (about 10%), Dysschema sacrifica (about 10%) and Halysidota ruscheweyhi (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mamerthes orionalis is recorded against all the insects logged in Buenos Aires (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.
