About Notodonta tritophus (Denis & Schiffermüller), 1775
Notodonta tritophus, commonly called the three-humped prominent, is a moth species belonging to the family Notodontidae. This species was first formally described by Michael Denis and Ignaz Schiffermüller in 1775. It is distributed across most of Europe, where it only occurs as a very rare immigrant to Great Britain, and its range extends eastward to the Caucasus and Armenia. The wingspan of adult Notodonta tritophus measures 45 to 55 mm. In western Europe, adult moths are active between April and August, and produce two generations per year. The larvae of this species feed primarily on Populus species, most commonly aspen (Populus tremula). They will occasionally also feed on willows (Salix species) and birch (Betula species). Larvae can be found from June to September. Notodonta tritophus overwinters in its pupal stage.
