Morley's Final Catalogue: This central European Prominent is of extreme rarity throughout Britain. Of the few indigenous specimens recorded, we boast two. An example was taken at a gas-lamp at Ipswich about 1867 (Exhibited before Entom. Soc. Lond. in April 1877); and a male similarly flew to light in a shop-window at Southwold, 1884, 253). None later recorded.
Recent Suffolk Status: A very rare immigrant with just four modern records of individuals light-trapped on the coast: Walberswick on 24.07.1992 (per B. Skinner), Bawdsey Hall on 18.08.2012 (M.J. Deans), Kessingland on 03.08.2017 (A. Eaton) and Hollesley on 01.08.2019 (R. Watson).
Life history: Double-brooded on the continent.
Identification: Obviously larger and darker than the other prominent species. The name derives from the caterpillar which has three humps on it's back.
Habitat: Wetlands and wet woodland in Europe. Coastal in the UK.
