 from the tree when wounded. 



Nearly all the species towards the end of 

 summer enclose themselves in a double case, 

 in which they remain, many of them, all the 

 winter, before they change into the chrysalis 

 state. In about a fortnight or three weeks 

 after the change, the perfect insects appear.
