 low herbage ; others sail majestically round the tops of 

 trees, and are difficult to capture. Morpho Aurora, the 

 largest and one of the finest insects in the group, is said 

 to frequent plants growing on the sides of precipitous 

 rocks. Observe the resplendent Morplio Cypris from

 the power of seeking for and devouring food.
