may be other gold dots also, and outlining the apex 

 of the jewel, is a band of gold with a dotted lower edge 

 of jet; and the knob at the top, to which the silk 

 which suspends the chrysalis is fastened, is also jet. 

 The chrysalis changes to a darker blue-green after two 

 days, and black dots appear in the gold garniture. 

 As this chrysalis is usually hung to the under side of a 

 fence rail or overhanging rock, or to a leaf, it is 

 usually surrounded by green vegetation, so that its 

 green color protects it from prying eyes. Yet it is 

 hardly from birds that it hides; perhaps its little gilt 

 buttons are a hint to birds that this jewel is not 

 palatable. As it nears the time for the butterfly to 

 emerge, the chrysalis changes to a duller and darker 

 hue. The butterfly emerges about twelve days after 

 the change to a chrysalis.
