EYE SPY 
Again and again have I shaken or brushed 
them off only to see them increase and multiply ; 
and, on the other hand, on more than one occa- 
sion have I seen an entire swarm vanish from a 
particular twig which I knew was infested only a 
day or two previous. Why? It was not that the 
aphides had completed their growth and died or 
fled. A careful examination among the young 
leaves or along the stem in their neighborhood 
showed the author of the havoc, a fat aphis lion, 
perhaps, in the act of sucking the contents of 
its last victim, or, perhaps, having completed his 
growth, contemplating the commencement of his 
cocoon in which to abide during the winter.
