Rare
Under 5% of wildlife watchers report an Opisthius richardsoni sighting in Olympic National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 123rd 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 30%, if each day is a fresh chance.
February and April–May
In those months about 10% of wildlife watchers report an Opisthius richardsoni in Olympic National Park on a given day, against under 5% in March and June–January, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Opisthius richardsoni sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Olympic National Park, in our data
Olympic National Park is the only park on Wallace's Line with enough records to rate Opisthius richardsoni sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Carabidae
The closest relatives of the Opisthius richardsoni that you can see in Olympic National Park (family Carabidae, Ground Beetles) are Narrow-Collared Snail-Eating Beetle (about 20%), Western Tiger Beetle (about 10%) and Boreal Long-Lipped Tiger Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Opisthius richardsoni is recorded against all the insects logged in Olympic National Park (9 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.
