Rare
Under 5% of wildlife watchers report a Rosy Aemilia sighting in Rocky Mountain National Park on a given day, based on 5 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 and September–October
In those months about 10% of wildlife watchers report a Rosy Aemilia in Rocky Mountain National Park on a given day, against under 5% in July–August and November–May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Rosy Aemilia sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Rosy Aemilia sightings, Rocky Mountain National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Great Bear Rainforest (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Rosy Aemilia is recorded against all the insects logged in Rocky Mountain National Park (5 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.
