Forficula dentata is a species of earwig in the family Forficulidae, commonly referred to as the Western earwig or European earwig. It was first described by Danish zoologist, Johan Christian Fabricius, in 1775. It is a cryptic species belonging to the Forficula auricularia species complex. Originally thought to be a synonym of F. auricularia, it has since been classified its own unique species. Being cryptic, it is often misidentified as F. auricularia or Forficula mediterranea, which differ in their distribution.
The distribution of F. dentata includes the British Isles, parts of Western Europe, Australia, New Zealand, Chile, the Western United States and Canada. Other populations of this species include the Belarusian Central Botanic Gardens, Belarus; Newfoundland, Canada; and an individual near Gimmingen, Germany. Wikipedia →

No species of the same family or order lives in Portland, so these are its closest relatives here: other insects.
With luck
About 10% of wildlife watchers report a Western Earwig sighting in Portland on a given day, based on 199 verified sightings from GBIF citizen-science data. It is the 32nd most-seen of the 507 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Western Earwig in Portland on a given day, against about 10% in December to October, the lowest months. That is one of Portland's wettest months, with about 220 mm of rain against 10 mm in July.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Western Earwig sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 15 cities where we can rate Western Earwig sightings, Portland has the highest daily chance: about 10%. Next come Melbourne (Australia, about 10%) and La Paz (Bolivia, about 10%).
GBIF citizen-science records
It is estimated from how often the Western Earwig is recorded against all the insects logged in Portland (199 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.
