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 →

With luck
About 10% of wildlife watchers report a Western Earwig sighting in Channel Islands National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 63rd most-seen of the 131 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.

In that month about 20% of wildlife watchers report a Western Earwig in Channel Islands National Park on a given day, against under 5% in March and August–November, the lowest months. That is one of Channel Islands National Park's wettest months, with about 55 mm of rain against almost none 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.
Among the best
Of the 9 parks where we can rate Western Earwig sightings, Channel Islands National Park ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Monfragüe National Park (Spain, about 10%), Pacific Rim National Park Reserve (Canada, about 10%) and Redwood National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Western Earwig is recorded against all the insects logged in Channel Islands National Park (14 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.
