212 BUTTERFLIES 



grown in May when they change to chrysaHds, to emerge 

 as the first brood of butterflies the following month. 

 Many of the caterpillars make a sort of nest for them- 

 selves by spinning a web of silk upon the imder surface of 

 the leaf and drawing together slightly the outer edges. 



As is the case with so many other butterflies that 

 hibernate as caterpillars, apparently the species is only 

 partially double-brooded. Some of the earlier caterpillars 

 become lethargic when half grown and remain in that 

 condition throughout the later weeks of summer and all 

 through the fall and winter. {See plate, page 209.) 



The Tawny Emperor 



Chlorippe clyton 



This handsome butterfly is easily distinguished from the 

 Gray Emperor by the general reddish color of the wings 

 which are thickly marked with bands and eye-spots of 

 darker brown or black. The eye-spots are especially 

 marked on the hind wing, there being a row of five of these 

 on each hind wing in both sexes. The females are de- 

 cidedly larger than the male and generally of a dis- 

 tinctly lighter color. {See plate, page 209.) 



This butterfly is a southern species found more or less 

 abundantly from southern New York to northern Florida 

 and across the country to a line drawn from Iowa to Texas. 

 It seems to be more common in the Mississippi Valley than 

 in other regions and its life-history was first thoroughly 

 worked out in Missouri and published in one of Riley's 

 classic reports on the insects of that state. It has since 

 been studied by Edwards and others, but even now there
