BUTTERFLIES AND MOTHS 



captured by Mr. Arnold Hodson m southwestern Abyssinia 

 on November 15, 1925. Four of the models, of which one 

 is represented in 5, were taken in the same locality on the 

 same day. 



It should be added that other nauseous butterflies are 

 mimicked by other female forms of the same swallowtail, 

 as well as by very different butterflies and by day-flying 

 moths. Four out of the five Abyssinian mimetic females 

 resemble 6, but the fifth, at Prague, exhibits the very dif- 

 ferent colouring of another model. 



Examples could be multiplied indefinitely, but I believe 

 that those here described afford sufficient evidence that pre- 

 dictions based on evolution are verifiable and have been veri- 

 fied, and that natural history becomes in the light of evolu- 

 tion a living and inspiring study. 



Although there are widely different opinions about the 

 causes of evolution, it is probable that no living student of 

 nature has any doubt about the truth of Evolution.
