PORTRAIT OF A BUTTERFLY-IN-THE-MAKING 



The two-inch caterpillar of the tiger swallowtail is particularly startling in appear- 

 ance because of two colorful spots on its head, which look like hypnotic eyes. Jusf 

 back of its head it is equipped with a scent organ which it can thrust out to produce 

 a disagreeable odor that drives off birds that would otherwise make a meal of it.
