Rare
Under 5% of wildlife watchers report a Root Maggot Fly sighting in Chicago on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 560th most-seen of the 978 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 Root Maggot Fly in Chicago on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Root Maggot Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
30th of 30
Of the 30 cities where we can rate Root Maggot Fly sightings, Chicago ranks 30th at under 5%. The best odds are in Tel Aviv (Israel, about 10%), Hyderabad (India, about 10%) and Athens (Greece, about 10%).
Same order: Diptera
The closest relatives of the Root Maggot Fly that you can see in Chicago (order Diptera, Flies) are Margined Calligrapher (about 10%), Narrow-Headed Marsh Fly (about 10%) and Common Picture-Winged Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Root Maggot Fly is recorded against all the insects logged in Chicago (12 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.
