Rare
Under 5% of wildlife watchers report a Gnathacmaeops pratensis sighting in Rocky Mountain National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 146th most-seen of the 191 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.
May and June
In those months about 10% of wildlife watchers report a Gnathacmaeops pratensis in Rocky Mountain National Park on a given day, against under 5% in July to April, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Gnathacmaeops pratensis sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate Gnathacmaeops pratensis sightings, Rocky Mountain National Park ranks 5th at under 5%. The best odds are in Denali National Park (United States, about 10%), Jasper National Park (Canada, about 10%) and Yellowstone National Park (United States, about 10%).
Same family: Cerambycidae
The closest relatives of the Gnathacmaeops pratensis that you can see in Rocky Mountain National Park (family Cerambycidae, Longhorn Beetles) are White-Spotted Sawyer (about 30%) and Spotted Pine Sawyer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gnathacmaeops pratensis is recorded against all the insects logged in Rocky Mountain National Park (7 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.
