With luck
About 10% of wildlife watchers report a Martha's Pennant sighting in Acadia National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 224th most-seen of the 405 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Martha's Pennant in Acadia National Park on a given day, against under 5% in September to May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Martha's Pennant sightings with a recorded time, and about 9 in 10 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 Martha's Pennant sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Martha's Pennant is recorded against all the insects logged in Acadia National Park (23 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.
