With luck
About 10% of wildlife watchers report a Kearfott's Petrophila sighting in Edmonton on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 111th most-seen of the 390 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Kearfott's Petrophila in Edmonton on a given day, against under 5% in September to June, the lowest months. Those are among Edmonton's wettest months, with about 75 mm of rain a month against 20 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Kearfott's Petrophila sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Edmonton, in our data
Edmonton is the only city on Wallace's Line with enough records to rate Kearfott's Petrophila sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Kearfott's Petrophila is recorded against all the insects logged in Edmonton (25 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.
