With luck
About 10% of wildlife watchers report a Black-Smudged Chionodes Moth sighting in Shenandoah National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 406th 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 30%, if each day is a fresh chance.
April–May and August
In those months about 10% of wildlife watchers report a Black-Smudged Chionodes Moth in Shenandoah National Park on a given day, against under 5% in June–July and September–March, the lowest months.

Across all the parks we cover, that three-hour window holds the most Black-Smudged Chionodes Moth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Shenandoah National Park, in our data
Shenandoah National Park is the only park on Wallace's Line with enough records to rate Black-Smudged Chionodes Moth 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-Smudged Chionodes Moth is recorded against all the insects logged in Shenandoah National Park (12 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.
