CHAPTER XI. 
WASPS. 
I 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. 
{ 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. 
Experiment 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. ] 
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,
