BUTTERFLIES AND MOTHS OF THE GREEN LANES. 157 



in some similar manner, both from observation 

 and injury. Again, the eyes of a butterfly are very 

 much larger than those of a moth, because the 

 butterfly flies by day. The waist of a butterfly 

 is nipped in, making the division into thorax and 

 body very distinct ; but there is no such distinct 

 division in a moth." 



Let us notice a few of the commoner forms, both 

 of moths and butterflies, that literally intrude 

 themselves on our notice during a country walk. 

 You have not to hunt them, they are so common. 

 The rarer species we leave to the regular entomo- 

 logist, who knows their habits, and the places where 

 they will be found, if they are to be met with at all. 

 Perhaps we have no British butterfly better known 

 than the Large White Cabbage (Pieris brassier), 

 whose eggs and scales we have already noticed. In 

 this as in nearly all species, both of butterflies and 

 moths, the female is the larger insect. The Smaller 

 white butterfly (P. rapse) is a diminutive copy of the 

 former, but with the blotches at the tips of the 

 wings less dark. The green-veined White (P. napi) 

 has its own pithy description in its common name.

 species are double-brooded, the eggs being usually 

 laid on cruciferous plants. Both species also have 

 strong migratory habits, and frequently collect in 

 large flocks, even crossing the sea. A more elegant 

 and attractive insect, and one you are sure to meet
