The Herald Scoliopteryx libatrix
Wingspan 40-45 mm.
Quite a spectacular species, this colourful moth overwinters as an adult, and as a result, can be one of the last species to be seen in one year, and one of the first in the next. It is also sometimes found hibernating inside barns and outbuildings.
The adults are attracted to both light and sugar, and the species is fairly common and well distributed over much of Britain, though it is less common in Scotland.
The larvae feed on willow (Salix) and poplar (Populus).
