Rare
Under 5% of wildlife watchers report an Acerra normalis sighting in Yosemite National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd most-seen of the 227 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.
April
In that month about 20% of wildlife watchers report an Acerra normalis in Yosemite National Park on a given day, against under 5% in May to March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Acerra normalis sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Yosemite National Park, in our data
Yosemite National Park is the only park on Wallace's Line with enough records to rate Acerra normalis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Acerra normalis is recorded against all the insects logged in Yosemite 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.
