With luck
About 10% of wildlife watchers report a Noctueliopsis virula sighting in Death Valley National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 108 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.

In that month about 20% of wildlife watchers report a Noctueliopsis virula in Death Valley National Park on a given day, against under 5% in May to January, the lowest months. That is one of Death Valley National Park's wettest months, with about 25 mm of rain against 5 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Noctueliopsis virula sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Death Valley National Park, in our data
Death Valley National Park is the only park on Wallace's Line with enough records to rate Noctueliopsis virula sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Noctueliopsis virula is recorded against all the insects logged in Death Valley National Park (8 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.
