Rare
Under 5% of wildlife watchers report a Decorated Owlet sighting in Shenandoah National Park on a given day, based on 5 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.
May
In that month about 10% of wildlife watchers report a Decorated Owlet in Shenandoah National Park on a given day, against under 5% in June to April, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Decorated Owlet sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
3rd of 3
Of the 3 parks where we can rate Decorated Owlet sightings, Shenandoah National Park ranks 3rd at under 5%. The best odds are in Great Smoky Mountains National Park (United States, about 10%) and Acadia National Park (United States, under 5%).
Same family: Erebidae
The closest relatives of the Decorated Owlet that you can see in Shenandoah National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Spongy Moth (about 40%), Isabella Tiger Moth (about 30%) and Hickory Tussock Moth (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Decorated Owlet is recorded against all the insects logged in Shenandoah 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.
