Possible
About 20% of wildlife watchers report a Narrow-Collared Snail-Eating Beetle sighting in Olympic National Park on a given day, based on 109 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 207 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Narrow-Collared Snail-Eating Beetle in Olympic National Park on a given day, against under 5% in July and November–February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Narrow-Collared Snail-Eating Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Narrow-Collared Snail-Eating Beetle sightings, Olympic National Park ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Pacific Rim National Park Reserve (Canada, about 20%) and Redwood National Park (United States, about 20%).
Same family: Carabidae

GBIF citizen-science records
It is estimated from how often the Narrow-Collared Snail-Eating Beetle is recorded against all the insects logged in Olympic National Park (109 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.
