the adult pulls itself out. When the moth has escaped, bits of the 

 end of the pupa case project outside the burrow, and the empty 

 case may be forcibly extracted before it dries. If this Cossiis larva 

 pupated in the earth at the foot of the tree there would be a good 

 reason why it should have carried the burrow to the surface. As it 

 does not pupate outside the tree, and as it remains in the open air 

 only long enough to shape and smooth the opening, may we not 

 conclude that here is a worm which cares for its adult?
