152 BUTTERFLIES 



tinue to feed and grow rather rapidly until they become full 

 size. Each then fastens a bit of pink silk to the stem of 

 the plant or some other support, in which it entangles its 

 hind legs and hangs downward to become a chrysalis 

 which is remarkable for its numerous protuberances and 

 the beautiful silvery and golden spots along the middle of 

 the back. Within these chrysalids the change from larva 

 to butterfly takes place, usually in less than two weeks, 

 so that this new brood of adults appears on the wing early 

 in July. Eggs are laid by these for a second brood of 

 caterpillars that feed upon the host plants in the same way 

 as the others, and mature as butterflies late in August or 

 early in September. These butterflies visit the fall 

 flowers and suck the juices of fallen fruits, until the cold 

 weather of autumn warns them to seek shelter for the 

 winter. They now find crevices within the bark of trees 

 or places in hollow logs or stone piles or other similar 

 situations, where they close their wings together, so that 

 only the bark-like under surface shows, and remain quiet 

 for long periods. They hibernate in this way, coming 

 forth again the foUow^ing season to start the cycle for the 

 new year. 



In regions where hops are grown commercially the 

 chrysalids of these butterflies are often called "hop 

 merchants." There is a quaint fancy that the price of 

 the crop varies with the lustre of the golden spots upon 

 the chrysalids. When these stand out conspicuously, 

 according to this fancy, the hops are to sell high — bringing 

 much gold to the owners. When these are inconspicuous 

 the hops are to sell at a low price, with a corresponding 

 diminution in the returns. But this fancy does not apply 

 at all to the chrysalids when they are nearly ready to dis-
