THE MILKWEED BUTTERFLIES 235 



In this quiet chrysalis the insect remains for nearly a 

 fortnight. Then the structure of the forthcoming butter- 

 fly begins to show through the thin outer covering and you 

 know that the period of the chrysalis is nearly ended. If 

 you keep watch you will probably see the sudden bursting 

 of the outer envelope and the quick grasping of its surface 

 by the legs of the newly emerged butterfly. Its wings at 

 first are short and crumpled, bearing little resemblance to 

 those of the fully developed butterfly. But as it hangs 

 there with one pair of legs holding to the empty chrysahs 

 and the other to the leaf above, the wings rapidly lengthen, 

 hanging limply downward, and the body juices penetrate 

 the veins. A little later they expand in the other di- 

 rection, the hind wings reaching full size before the front 

 ones do. Finally both pairs of wings are fully expanded, 

 and the butterfly is likely to walk to the top of the sup- 

 port, where it rests for an hour or two while its tissues 

 harden, before it attempts to fly. 



In early autumn out of doors these butterflies start 

 southward on their long journey. They often gather in 

 great flocks and roost at night on wayside shrubs and 

 trees. At this season it is easy to catch them in an insect 

 net and bring them indoors for pets. They live for a long 

 while and lend interest and beauty to living room or window 

 garden. To the photographer they offer opportunities for 

 attractive indoor pictures. {See plates, pages 32-33, 160,

 show at once that it is related to the Monarch. Its gen-
