Possible
About 20% of wildlife watchers report a Northeastern Pine Sawyer sighting in Voyageurs National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 20 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Northeastern Pine Sawyer in Voyageurs National Park on a given day, against under 5% in May and June, the lowest months. That is one of Voyageurs National Park's wettest months, with about 110 mm of rain against 25 mm in January. November to April have too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Northeastern Pine Sawyer sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 parks where we can rate Northeastern Pine Sawyer sightings, Voyageurs National Park has the highest daily chance: about 20%. Next come Isle Royale National Park (United States, about 20%) and Riding Mountain National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Northeastern Pine Sawyer is recorded against all the insects logged in Voyageurs 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.
