Rare
Under 5% of wildlife watchers report a Gold-Striped Grass-Veneer sighting in Great Smoky Mountains National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 628th most-seen of the 822 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July and September
In those months about 10% of wildlife watchers report a Gold-Striped Grass-Veneer in Great Smoky Mountains National Park on a given day, against under 5% in August and October–June, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Gold-Striped Grass-Veneer sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Great Smoky Mountains National Park, in our data
Great Smoky Mountains National Park is the only park on Wallace's Line with enough records to rate Gold-Striped Grass-Veneer sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gold-Striped Grass-Veneer is recorded against all the insects logged in Great Smoky Mountains National Park (5 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.
