Notodonta tritophus, the three-humped prominent, is a moth of the family Notodontidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in most of Europe (although it is a very rare immigrant Great Britain), east to the Caucasus and Armenia.
The wingspan is 45–55 mm. Adults are on wing from April to August in two generations in western Europe. The larvae mainly feed on Populus species, mainly aspen (Populus tremula), and sometimes willows (Salix species) and birch (Betula species). Larvae can be found from June to September. The species overwinters in the pupal stage. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Three-Humped Prominent is recorded against all the insects logged in Pyrénées National Park (7 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.
