Hypena deceptalis
In 3 days ~20% in a week ~40%
Hypena deceptalis, the deceptive hypena or deceptive bomolocha moth, is a moth of the family Erebidae. The species was first described by Francis Walker in 1859. It is found in North America from Manitoba to Quebec, south to Florida and Texas. It is absent from much of Gulf Coastal Plain though.
The wingspan is 28–35 mm. The moth flies from April to August. There are two generations per year. The larvae feed on Tilia americana, but the species is also found outside of the range of Tilia americana, so there must be at least one other host. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Deceptive Snout is recorded against all the insects logged in Shenandoah National Park (19 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.
