With luck
About 10% of wildlife watchers report a F-Winged Barklouse sighting in Shenandoah National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 325th most-seen of the 723 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May and September–November
In those months about 10% of wildlife watchers report a F-Winged Barklouse in Shenandoah National Park on a given day, against under 5% in June–August and December–April, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most F-Winged Barklouse sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate F-Winged Barklouse sightings, Shenandoah National Park has the highest daily chance: about 10%. Next come Bavarian Forest National Park (Germany, about 10%) and Cévennes National Park (France, under 5%).
GBIF citizen-science records
It is estimated from how often the F-Winged Barklouse is recorded against all the insects logged in Shenandoah National Park (11 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.
