FAMILY PIERIDJE. 



(Whites and Yellows.) 



The popular names have been given to this family 

 on account of the predominance of white and yellow 

 colours. These butterflies have a wide range. 

 Waterhouse and Lyell j-ecords: ''It is within this 

 family that the migratory habit is most noticeable, 

 both in Australia and elsewhere. We have observed 

 several immense flights of Anaphacis Java teutonia 

 and Catopsila pythias in the neighbourhood of 

 Sydney, and their direction has invariably been 

 from north to south; on the other hand, flights of 

 teiitonia we have noted in Gisborne have all been 

 travelling almost due north. During these flights 

 all the butterflies seemed to be steadily pursuing 

 the one course, only occasionally visiting a flower 

 and rarely resting until evening, excepting possibly 

 for a time Avliile a heavy cloud obscured the sun. 

 In the evening and through the night these 

 migratory butterflies often rest in company: scores 

 of teutonia have many times been noticed settled 

 on one small l)ough. They always choose for a 

 resting place those plants or trees which blend 

 most closely with their own colours."
