Rare
Under 5% of wildlife watchers report a Witchhazel Leafminer sighting in Shenandoah National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th most-seen of the 723 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.
September and October
In those months about 10% of wildlife watchers report a Witchhazel Leafminer in Shenandoah National Park on a given day, against under 5% in November to August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Witchhazel Leafminer sightings with a recorded time, and nearly all 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 Witchhazel Leafminer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Gracillariidae

GBIF citizen-science records
It is estimated from how often the Witchhazel Leafminer is recorded against all the insects logged in Shenandoah National Park (6 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.
