Rare
Under 5% of wildlife watchers report a Polybiomyia signifera sighting in Mexico City on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 320th 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 a Polybiomyia signifera 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 Polybiomyia signifera sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae
The closest relatives of the Polybiomyia signifera that you can see in Mexico City (family Syrphidae, Hover Flies) are Common Drone Fly (about 10%), Toxomerus mutuus (about 10%) and Dioprosopa clavatus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Polybiomyia signifera is recorded against all the insects logged in Mexico City (21 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.
