Rare
Under 5% of wildlife watchers report a Black-Tipped Darner sighting in Acadia National Park on a given day, based on 7 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.
July and September–October
In those months about 10% of wildlife watchers report a Black-Tipped Darner in Acadia National Park on a given day, against under 5% in August and November–June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-Tipped Darner sightings with a recorded time, and about 7 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 Black-Tipped Darner sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-Tipped Darner is recorded against all the insects logged in Acadia National Park (7 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.
