With luck
About 10% of wildlife watchers report a Three-Banded Robber Fly sighting in Point Pelee National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 105th most-seen of the 196 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.

Point Pelee National Park is the only park on Wallace's Line with enough records to rate Three-Banded Robber Fly sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Three-Banded Robber Fly is recorded against all the insects logged in Point Pelee National Park (10 verified sightings from 2019 to 2026), 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.
