Largely White Butterflies 



A largely white Ijiitterfly is a common sight and a guess that it is 

 the Cabbage Bntterfly {J'iois rapcr) will almost always hit the mark. 

 There are really three kinds of white butterflies in the ICast whose 

 young feed on cabbage. Two of them are natives, but the third was 

 accidentally brought from Europe to the vicinity of Quebec about i860. 



EUROPEAN CABBAGE BUTTERFLY {Pieris rapa:)'k 

 Male (upper and undersides), above; Female, below 



Since that time, aided doubtless by further importations, it has spread 

 over the wdiole country and, like its compatriot the English sparrow, 

 seems to be driving its native relatives out of existence. The European 

 Cabbage Butterfly has the tips of the upper side of the front wings 

 black; there are two black dots on each of the front wings of the female 

 and one on those of the male; the under side of the hind wings is 

 yellow^ish and without markings. 



With us the Mustard White, or Immaculate Cabbage Butterfly, has 

 practically no markings on the upper surface of the wings, although in 

 other parts of the country it is subject to many interesting variations.
