CHAPTER XI. 



WASPS. 



1 HAVE also made a few experiments with wasps. 



So far as their behaviour, when they have discovered 

 a store of food, is concerned, what has been said with 

 reference to bees would apply in the main to wasps also. 

 I will give some of the details in the Appendix, and 

 here only refer very briefly to some of the experiments. 



Experiment 1. Watched a wasp, which I had accus- 

 tomed to come to my room for honey, from 9.36 A.M. to 

 6.25 P.M. She made forty-five visits to the honey, but 

 did not bring a single comrade. 



Expert/merit 2. The following day this wasp began 

 working at least, came to my room for the first time at 

 6.55 A.M., and went on passing backwards and forwards 

 most industriously till 6.17 P.M. She made thirty-eight 

 journeys, and did not bring a single friend. 



Experiment 3. Another wasp was watched from 

 6.16 A.M. till 6 P.M. She made fifty-one journeys, and 

 during the day five other wasps came to the honey. I 

 do not think she brought them. 



Experiment 4. Another wasp was watched from 

 10 A.M. to 5.15 P.M.; she made twenty-eight journeys,
