Rare
Under 5% of wildlife watchers report an Ianius mosca sighting in Mexico City on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 474th most-seen of the 557 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 an Ianius mosca in Mexico City on a given day, so our monthly data shows no clear season.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Ianius mosca sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Ianius mosca that you can see in Mexico City (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black Witch (about 20%) and Arachnis dilecta (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ianius mosca is recorded against all the insects logged in Mexico City (6 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.
