Rare
Under 5% of wildlife watchers report a Bicolored Carpenter Ant sighting in Olympic National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 182nd most-seen of the 207 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.
June
In that month about 10% of wildlife watchers report a Bicolored Carpenter Ant in Olympic National Park on a given day, against under 5% in July to May, the lowest months. That is one of Olympic National Park's driest months, with about 85 mm of rain against 370 mm in November.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Bicolored Carpenter Ant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Bicolored Carpenter Ant sightings, Olympic National Park ranks 4th at under 5%. The best odds are in Grand Canyon National Park (United States, about 10%), Redwood National Park (United States, about 10%) and Yosemite National Park (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Bicolored Carpenter Ant is recorded against all the insects logged in Olympic National Park (5 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.
