With luck
About 10% of wildlife watchers report a Black-And-Red Horntail 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 270th 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.
August
In that month about 10% of wildlife watchers report a Black-And-Red Horntail in Acadia National Park on a given day, against under 5% in September to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-And-Red Horntail 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 Black-And-Red Horntail sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-And-Red Horntail 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.
