In this c'Oiulition tlirougli the winter. 



'I'hi' tiioth sits duriiitr the (hiy upon the trunks of trees, 

 more esppcinliy o;U< and l)irc'ii trees, anil in cool weather ni;iy 

 be secured with great ease, but in liot sunshine is very rest- 

 less and active, or even will retire into the cooler shade of 

 the leaves. iSometimes, though not commonly, it may be 

 beaten out of a thick hedge. It especially favours open 

 woods, or well-woodi'd heaths and hills, but is not scarce in 

 more open districts if trees are ])lentiful. In such suitable 

 districts it occurs throughout England and Wales; also 

 Scotland so far as i\Ioray and \Vest Uoss, and its curious 

 variety (ilhocirnatn is there in ])roportion much more frecpient. 

 This variety seems to be absent from Jrelantl. 1 hough the 

 moth in its ordinary form is there sometimes abunilant, and 

 seems to frequent woods wherever they e.xist. 



Abroad, it lias a wide range through Central i-]urope, tiif 

 temperate ])ortions of Northern I'lurope. Northern Italy, the 

 Ural mountain district, Turtary. the Isle of Askold. and 

 Japan — where it is quite normal.
