Life Cycle Guide
Description
Wingspan: Male-42-60mm : Female-45-65mm
Worldwide Distribution: Europe east to Japan
UK Distribution: Southern England-found in Hampshire,Sussex,Berkshire & Surrey. Only scattered records elsewhere
UK Conservation Status -
Habitat: Established Oak woodlands
Similar Species -
Pupa: Pupates below ground
Overwinters as: Larva
Observations: Without doubt after seeing Willow Beauty's on a fences for some period the biggest impact of seeing this moth for the first time has to be its enormous size.
The central cross-lines converge at the dorsum sometimes joining completely to form a dark blotch,not quite seen in the specimen below.
The moth can vary between light and dark as can be the markings which sometimes provide a strong subterminal and terminal lines on the hind wing to the marking being almost absent altogether like the subspecies H.r.f.infuscata Staudinger,1871-blackish-grey background,markings weak
The moth is a nationally scarce species mainly found in the mature oak woodlands in southern England like those found in the New Forest.
The moth is found during the day on fences or tree trunks and is also attracted to the light trap.
