With luck
About 10% of wildlife watchers report a Small Tortoise Beetle sighting in Shenandoah National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 447th 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.
April and June–July
In those months about 10% of wildlife watchers report a Small Tortoise Beetle in Shenandoah National Park on a given day, against under 5% in May and August–March, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Small Tortoise Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and 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 Small Tortoise Beetle sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Small Tortoise Beetle is recorded against all the insects logged in Shenandoah National Park (9 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.
