78 BUTTERFLIES 



A little more than a month later they mature into butter- 

 flies which are Ajax, the summer form. 



In a similar way the Telamonides or late spring butter- 

 flies lay eggs soon after they appear, also upon papaw 

 leaves, and these eggs in about a month mature into Ajax, 

 the summer form. 



So we have Ajax, the summer form, developing directly 

 from both the early spring or Marcellus and the late spring 

 or Telamonides butterflies. 



These Ajax butterflies in their turn lay eggs for cater- 

 pillar young. These soon mature into a brood of butter- 

 flies which are of this same Ajax form. There may be 

 successive broods through the summer, practically all of 

 them being this same Ajax summer form. 



The last brood of caterpillars, however, change to 

 chrysalids wliich do not disclose the butterflies until the 

 following spring. And then the first that come out are the 

 Marcellus form and the last the Telamonides form. So we 

 may have these two forms maturing from the same brood 

 of autumn caterpillars. 



This seems a sufficiently complicated life-history to suit 

 the most persistent solver of puzzle problems, but there is 

 an additional factor which adds much to the possible con- 

 fusion of the broods. In each brood of caterpillars from 

 the earliest to the latest there are a certain number of 

 chrysalids which remain dormant through the remainder 

 of the season and the following winter, maturing into 

 butterflies the next spring. Consequently at the end of 

 every winter there are a miscellaneous lot of chrysalids 

 which represent every brood of caterpillars that lived the 

 previous season, and all of these develop into either Mar- 

 cellus or Telamonides butterflies.
