HOW TO KNOW THE BUTTERFLIES 



part of the females are pale, looking distinctly 

 anaemic when compared with their brilliant sis- 

 ters. The orange sulphur has had to adapt itself 

 to various conditions. It has to summer in 

 Texas, where its food-plant occurs only during 

 the fall and winter ; and it has to winter in the 

 north, after the food-plant is frozen. It has been 

 a source of great entertainment to the ento- 

 mologists of the past who were species hunters, 

 and they have described its different forms as dis- 

 tinct species. The records show that it has the 

 following baptismal names : eurytheme, chryso- 

 theme, hagenii, eriphyle, edusa, barbara, harfordii, 

 keewaydin, ariadne, amphidusa and others. It 

 can be seen from the above that this butterfly, 

 which looks like a California poppy blown off the 

 stem, can compete successfully in names with 

 any of the crowned heads of Europe. 



The species is most abundant in the Mis- 

 sissippi Valley ; but it is found on the Pacific 

 coast and also along the Atlantic coast as far as 

 Maine. It is very much like the roadside butter- 

 fly in its habits, being an active flyer and social in 

 its disposition. 



This insect is from two- to four-brooded, de- 

 pending on the locality ; and it winters in both 

 the adult and larval states.
