73.260 [B&F: 2149] Silvery Arches (Polia hepatica) (Clerck, 1759)

 

Nationally scarce (Nb) in wooded heathland, moorland and open woodland, in Britain. In Hampshire local and uncommon in heathy areas, where the larvae can be found at night in spring, feeding on the opening buds of birch saplings growing amongst heather. This species has all but disappeared from the New Forest and north-east Hampshire, as well as from places in the centre of the county where the habitat has been destroyed. Not recorded from the Isle of Wight since 1980. Wingspan 43-52 mm. Fairly unmistakable. Larva feeds on Silver Birch, Downy Birch, Sallow, Bog-myrtle, Hawthorn and Honeysuckle.
