LAPPET-MOTH. 
205 
It feeds on a variety of trees and shrubs, such as 
the vi’illow, blackthorn, bramble, hawthoni, &c., 
and it is asserted that the colour varies according to 
the nature of its food. The cocoon which it spins 
for its pupal change is long, and generally tapers 
somewhat at one end. Tlie tissue is not very thick 
or compact, but all the interstices are closely filled 
up with a whitish powder, employed for lining the 
interior. The moth is found occasionally in many 
parts of England hut seldom in great abundance. 
It is not rare on the continent.
