THE GREEN-VEINED WHITE 31 



PLATE XVI 

 THE GREEN-VEINED WHITE (5) 



From a little distance you might very easily 

 mistake this butterfly for a " small white " ; for it 

 is of just the same size, and the upper surface 

 of its wings is marked in almost exactly the same 

 way. But if you happen to see it sitting with 

 its wings closed, you will notice at once that the 

 veins on the lower surface of the hinder pair are 

 streaked with green or grey. It is not quite as 

 common as the " small white," but you may see it 

 flying about in almost any part of the country 

 in May, and again in August. 



This butterfly lays its eggs on hedge-garlic, 

 and also on winter-cress and sometimes on water- 

 cress. They are most beautiful little objects if 

 you look at them through a microscope, for they 

 are shaped just like little tiny sugar-loaves, with 

 ridges running down them from the top to the 

 bottom, and smaller ridges crosswise between 

 them. The caterpillars which hatch out of them 

 are darker green above and lighter green below, 

 with a row of little black spots on either side, 

 each of which is enclosed in a yellow ring ; and 

 the chrysalis is green, sprinkled all over with 

 the tiniest possible black spots.
