The Hunting Wasps 



for the Ammophila ; for it is the second time 

 that she has met with the same mishap. 



The insect appears discouraged. In vain 

 I replace the caterpillar by one of my reserve 

 of Grey Worms: the Ammophila scorns the 

 substituted prey. Besides, evening is draw- 

 ing in, the sky has clouded, there are even a 

 few drops of rain falling. In these circum- 

 stances, it is needless to look for a renewal 

 of the chase. Everything, therefore, ends, 

 without my being able to use my Grey Worms 

 as I had proposed. 



This observation kept me engaged, with- 

 out a moment's respite, from one o'clock in 

 the afternoon until six o'clock in the evening.
