Rare
Under 5% of wildlife watchers report a Diplolepis spinosa 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 172nd 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.
June
In that month about 10% of wildlife watchers report a Diplolepis spinosa in Rocky Mountain National Park on a given day, against under 5% in July to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Diplolepis spinosa sightings with a recorded time, and about 9 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 Diplolepis spinosa sightings, Rocky Mountain National Park ranks 4th at under 5%. The best odds are in Riding Mountain National Park (Canada, about 20%), Elk Island National Park (Canada, about 10%) and Acadia National Park (United States, about 10%).
Same order: Hymenoptera
The closest relatives of the Diplolepis spinosa that you can see in Rocky Mountain National Park (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Hunt's Bumble Bee (about 10%), Nevada Bumble Bee (about 10%) and Colorado Black-Notched Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Diplolepis spinosa 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.
