Rare
Under 5% of wildlife watchers report a Snow-Born Boreus sighting in Acadia National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 304th most-seen of the 405 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.
February
In that month about 40% of wildlife watchers report a Snow-Born Boreus in Acadia National Park on a given day, against under 5% in March to December, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Snow-Born Boreus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Acadia National Park, in our data
Acadia National Park is the only park on Wallace's Line with enough records to rate Snow-Born Boreus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Snow-Born Boreus is recorded against all the insects logged in Acadia National Park (6 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.
