252 THE MOTHS OF THE BRITISH ISLES. 



coronet ; the lower angle is, however, most distinct, therefore 

 Haworth's English name seems most suitable as it indicates 

 the V-mark, which is a noticeable character of this delicate 

 green species. (Plate 100, Fig. i.) 



The caterpillar is yellowish green, with three reddish lines 

 along the back, the central one most distinct and sometimes 

 forming triangular marks, or lozenges. The ground colour 

 varies, and may be greener, yellower, or occasionally greyish ; 

 and the markings are not always present. 



There are two generations, the first in June and July, and the 

 second in the autumn, and in confinement a third brood is 

 sometimes obtained. The blossoms of various plants are 

 eaten, but those of hemp-agrimony (^Eupatorium cannabinuin)^ 

 golden-rod {Solida^o), clematis, and purple loosestrife {^Ly thrum 

 salicana), are perhaps favourites. Hawthorn and bramble 

 have also been mentioned as food plants. 



The moth is out in most of the months from May to August, 

 but seems to be most frequent in the first named. 



Generally distributed in the southern half of England, 

 extending into South Wales, rare in Yorkshire and in Rox- 

 burghshire, Scotland. Widely distributed in Ireland. The 

 range abroad extends to Japan.
