Perispasta is a genus of moths of the family Crambidae. It contains only one species, Perispasta caeculalis, or Titian Peale's pyralid moth, which is found in North America, where it has been recorded from Quebec west to British Columbia, south to Florida, Texas and Colorado. The habitat consists of fields and meadows. Both the genus and species were first described by Philipp Christoph Zeller in 1875.
The wingspan is 16–18 mm. The forewings are dark brown with a white discal bar. The hindwings are white. Adults have been recorded on wing from January to November, depending on the location. Wikipedia →

With luck
About 10% of wildlife watchers report a Titian Peale's Moth sighting in Shenandoah National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 325th 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 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Titian Peale's Moth in Shenandoah National Park on a given day, against under 5% in October to July, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Titian Peale's 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 Titian Peale's Moth sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Titian Peale's Moth that you can see in Shenandoah National Park (family Crambidae, Crambid Snout Moths) are Basswood Leafroller Moth (about 10%), Hollow-Spotted Blepharomastix Moth (about 10%) and Celery Leaftier Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Titian Peale's Moth is recorded against all the insects logged in Shenandoah National Park (13 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.
