SERICORID^—HED YA. 7 



September till April or May, on sallow, hawthorn and 

 aspen ; sometimes on oak and hazel ; feeding in spring on 

 the young shoots, eating into the substance at the heart, 

 hibernating in a little gallery on the surface of a twig 

 and under the shelter of a bud ; Sorhagen says that it 

 pupates under moss in a thick cocoon ; Fischer says in an 

 earth cocoon. 



A lively, bright-looking, active species, sitting by day in 

 trees and bushes and easily disturbed, when it flies swiftly 

 to a similar hiding-place. At sunset to dusk it flies high 

 round the upper branches of trees and seems especially 

 partial to oaks. Very common throughout the southern half 

 of England ; more local in Staffordshire, Cheshii^e, Lanca- 

 shire, Yorkshire, and Durham ; and in Scotland very local in 

 the Clyde district. In Wales common in Glamorganshire 

 and Pembrokeshire ; and in Ireland found at Cork, Sligo 

 and Derry. Abroad it inhabits the whole of Central Europe, 

 and Northern Europe except the polar region, also found in 

 Central and Northern Italy ; and in North America recorded 

 from California.
