Larva. Early stages : creamy buff with dorsal, subdorsal, and 

 sublateral series of small warts bearing tufts of long buff hairs ; 

 four pairs of prolegs, the 6th somite being without prolegs ; the 

 cast skins of the head are attached to a long tuft of hair projecting 

 forward from 1st somite, so that the number of moults can be 

 counted by the number of skins present. 



The full-grown larva is snow-white, covered with a down-like
