The Bot- Flies 



The life history of this insect was entirely misunderstood 

 until recent years. It was supposed that the eggs were laid upon 

 the back and that the larva immediately penetrated the skin and 

 lived there without wandering. It was not until 1890 that the 

 true life history, as described above, was ascertained by Dr. 

 Cooper Curtice.
