No. 538] THE BEHAVIOR OF BEES 613 



At (c) control. Petals only as in the preceding ex- 

 periment. 



Bees have been very little attracted by the artificial 

 cloth petals at (a). Although the color is not precisely 

 that of a cotton blossom, several bees gave evidence of 

 having perceived them. The texture, which is that of 

 coarse meshed cloth, is quite unlike that of cotton petals, 

 however, and may have been readily perceived as un- 

 real by the bees. The few inspections were without 

 doubt invited by the color of the artificial petals, since 

 no odors could be considered operative unless of a repel- 

 lent nature. 



Experiment No. 5. — July 26. Time of observation 

 one half hour, from 11:45 to 12:15 a.m. Blossoms in the 

 triangular arrangement with the following changes: 



At (a) five cotton petals (normal number) are care- 

 lessly placed over the artificial cloth petals. 



At (6) control. Same blossom entire as in the pre- 

 ceding experiments. 



At (c) petals alone as in the preceding experiments.
