Rare
Under 5% of wildlife watchers report a Pseudomasaris vespoides sighting in Rocky Mountain National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 136th 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.
July
In that month about 10% of wildlife watchers report a Pseudomasaris vespoides in Rocky Mountain National Park on a given day, against under 5% in August to June, the lowest months. That is one of Rocky Mountain National Park's wettest months, with about 95 mm of rain against 40 mm in September.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Pseudomasaris vespoides sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Pseudomasaris vespoides sightings, Rocky Mountain National Park ranks 2nd at under 5%. The best odds are in Yosemite National Park (United States, about 10%).
Same order: Hymenoptera
The closest relatives of the Pseudomasaris vespoides 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 Pseudomasaris vespoides is recorded against all the insects logged in Rocky Mountain 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.
