1 84 COMMON BRITISH INSECTS. 



costal edge of the lower wings. The females are at 

 once distinguished by having two black spots on the 

 disc of the upper wings. The caterpillar is a pretty 

 green larva, and is a very indiscriminate feeder. I 

 have bred a long series of them from mignonette 

 growing in a window-box. The Butterfly appears in 

 the midst of summer. 



The GREEN-VEINED WHITE (Pieris Napi) may 

 be known by the peculiarity from which it takes its 

 name. When inspected from below, the under surface 

 of the lower wings is seen to be dull yellow, the 

 nervures being edged with a greyish tint, which has 

 the effect of green when contrasted with the yellow. 

 The upper wings have much the same colouring, but 

 not so strongly marked except at the tips. This 

 caterpillar feeds on the watercress and one or two 

 other plants. 



CLOSELY allied to the Whites is the beautiful 

 ORANGE-TIP (Anthocharis card amines), so well known 

 by the orange-tipped wings of the male, from which 

 it derives its popular name. The female is without 

 the orange hue, but both sexes have the under side of 

 the lower wings beautifully mottled with green. The 

 insect is as plentiful as it is beautiful, and may be 

 captured in almost every meadow or lane in the early 

 summer. It does not fly very fast, and generally 

 keeps rather low, so that there is no difficulty in taking 

 it. The caterpillar feeds on various cruciform plants, 

 and its colour is opaque green.
