Clouds of Butterflies (Lap.). 



I have seen clouds of butterflies, all of the same species, passing over 

 a district [in the Congo] for three months at a time, like flakes of red 

 snow, and in such close array that one could destroy dozens of them 

 by throwing one's hat on the ground. The real savage beast of Equa- 

 torial Africa, and the most formidable, is the insect. — Cureau, Savage 

 Alan in Central Africa, London [n. d. 191 5], pp. 217-218.
