Under 5% of wildlife watchers report a Long-Haired June Beetle sighting in Portland on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 402nd most-seen of the 507 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.

GBIF citizen-science records
It is estimated from how often the Long-Haired June Beetle is recorded against all the insects logged in Portland (7 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.
