94 BRITISH BUTTERFLIES AND MOTHS 



It is yellowish, spotted with black, and has a row of 

 raised black spots on each side of the back. (See wood- 

 cut at p. 7, Fig. 1.) It feeds in June and September 

 on cabbages, sometimes nearly stripping them of their 

 leaves ; it is also partial to the various species of Tro- 

 pseolum. Few larvae are more subject to the attacks of 

 parasitic insects than this, and in autumn we frequently 

 see one of these larvae dead or dying on a wall or paling, 

 resting on a number of small yellow cocoons, which are 

 the cocoons spun by the parasitic larvae which have fed 

 within its body. 



The perfect insect may be met with almost constantly 

 from the end of April to the middle of August, though 

 at the end of June and beginning of July there is gene- 

 rally a slight intermission between the two broods. 



The Small White Butterfly (Pieris rapse), and the 

 Green-veined White (Pieris napi), are equally plenti- 

 ful throughout the country. Both are readily distin- 

 guished from the Large White Butterfly by their smaller 

 size, and the Green- veined White is readily recognized 

 by the greenish veins on the underside of the hind- 

 wings. 



One of our rarest native butterflies is the Bath White 

 (Pieris Daplidice). It is sometimes found in August in 

 the south of England.
