THE MILKWEED 



237 



capture is somewhat similar to the milkweed. 

 The anthers are divided by a V-shaped cavity, 

 into which the insect's tongue is guided as it is 

 withdrawn from the flower, and into which it 

 often becomes so tightly wedged as to render es- 

 cape impossible. I have found small moths dan- 

 gling by the tongue, as seen in the illustration 

 below.
