Rare
Under 5% of wildlife watchers report a Mottled Snout sighting in Shenandoah National Park on a given day, based on 8 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.
April, July and September
In those months about 10% of wildlife watchers report a Mottled Snout in Shenandoah National Park on a given day, against under 5% in May–June, August and October–March, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Mottled Snout 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 Mottled Snout sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Hypena
The closest relatives of the Mottled Snout that you can see in Shenandoah National Park (genus Hypena) are Green Cloverworm Moth (about 10%), Deceptive Snout (about 10%) and Baltimore Snout (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mottled Snout is recorded against all the insects logged in Shenandoah 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.
