With luck
About 10% of wildlife watchers report a Cotton-Gall Tephritid sighting in Denver on a given day, based on 95 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 461 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Cotton-Gall Tephritid in Denver on a given day, against under 5% in June–August and November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cotton-Gall Tephritid sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Denver, in our data
Denver is the only city on Wallace's Line with enough records to rate Cotton-Gall Tephritid sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cotton-Gall Tephritid is recorded against all the insects logged in Denver (95 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.
