Rare
Under 5% of wildlife watchers report a Mottled Grass-Veneer sighting in Chicago on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 473rd 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 Mottled Grass-Veneer 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 Mottled Grass-Veneer sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Mottled Grass-Veneer is recorded against all the insects logged in Chicago (23 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.
