 these thorns, it is evident that all ordinary foes would be baffled 

 by such an array of points, no matter how anxious they might 

 be to get at the creature within. 



The thorns are equally efficient as a means of concealment, 

 for, as they are taken from the tree itself, they cause the nest to 

 harmonize so perfectly with surroxmding objects, that it is not 

 very easily perceived. 



As long as the caterpillar remains in its larval state, and is 

 obliged to feed, it traverses the branches freely, carrying with it 

 the prickly home, and bearing the whole of its weight as it 

 moves. But when the pupal stage has nearly arrived, the nest is 

 suspended to the branch by strong silken threads, and thence- 

 foi-th remains immoveable.
