With luck
About 10% of wildlife watchers report a Penthetria heteroptera sighting in Shenandoah National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 156th 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 50%, if each day is a fresh chance.
November
In that month about 40% of wildlife watchers report a Penthetria heteroptera in Shenandoah National Park on a given day, against under 5% in December to August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Penthetria heteroptera 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 Shenandoah National Park, in our data
Shenandoah National Park is the only park on Wallace's Line with enough records to rate Penthetria heteroptera sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Penthetria heteroptera is recorded against all the insects logged in Shenandoah National Park (26 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.
