Rare
Under 5% of wildlife watchers report a Sawtooth Sunflower Midge sighting in Chicago on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 505th 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 Sawtooth Sunflower Midge in Chicago on a given day, so our monthly data shows no clear season.
Only Chicago, in our data
Chicago is the only city on Wallace's Line with enough records to rate Sawtooth Sunflower Midge sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sawtooth Sunflower Midge is recorded against all the insects logged in Chicago (16 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.
