Peridea ferruginea, the chocolate prominent, is a species of prominent moth in the family Notodontidae. It was described by Alpheus Spring Packard in 1864 and is found in North America. In 2018, Miller et al. distinguished Peridea bordeloni, whose larvae specialize on river birch Betula nigra, as a separate species, though P. bordeloni has previously been identified as P. ferruginea.
The MONA or Hodges number for Peridea ferruginea is 7921. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Chocolate Prominent is recorded against all the insects logged in Acadia National Park (20 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.
