 useless small insects, and they can only be 

 reached by the long proboscis of the bee or 

 the butterfly. To prevent ants, small beetles, 

 and other honey-eating intruders from creep- 

 ing up the stalk, and so rifling the nectaries

 so many precautions were not enough, the 

 mouth of the tube, above the stamens, is
