With luck
About 10% of wildlife watchers report a Pygoctenucha terminalis sighting in Rocky Mountain National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 110th most-seen of the 191 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Pygoctenucha terminalis in Rocky Mountain National Park on a given day, against under 5% in October to May, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Pygoctenucha terminalis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Rocky Mountain National Park, in our data
Rocky Mountain National Park is the only park on Wallace's Line with enough records to rate Pygoctenucha terminalis sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae

GBIF citizen-science records
It is estimated from how often the Pygoctenucha terminalis is recorded against all the insects logged in Rocky Mountain 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.
