TRIFID.E. 203 



This moth also has been found on rare occasions llyintj- 

 in uiultitudes about sallows in the hot midday sunshine. 

 Ordinarily it spends this portion of its time hidden on the 

 o-rouud amoim dead leaves. At dusk it crowds with its 

 congeners to the sallow blossoms, and forms perhaps the 

 largest fraction of the shower of moths brought down when 

 the bush is shaken. When the freshness of the sallow-bloom 

 is over it will resort to the ilowers of plum and blackthorn, 

 but hardly ever to sugar. 



Most partial to woods, but found everywhere where trees 

 are common, and plentiful throughout England, Wales, and 

 Ireland; also in more moderate numbers over the greater 

 part of Scotland— everywhere, apparently, where there are 

 woods, but not recorded from any of the Isles. Abroad it 

 is not a northern species, and its range seems to be mainly 

 through portions of Central and Southern Europe, yet must 

 extend into some portions of Asia, since it is found both in 

 its drab and red-drab forms in Japan.
