14 BEHAVIOB 01* HONEY BEE llf POLLEN COLLECTING. 



ACTIOIT OF THE MIDDLE LEGS. 



The middle legs are used to collect the pollen gathered by the 

 forelegs and mouthparts, to remove free pollen from the thoracic 

 region, and to transport their load of pollen to the hind legs, placing 

 most of it upon the pollen combs of these legs, although a slight 

 amount is directly added to the pollen masses in the corbiculse. Most 

 of the pollen of the middle legs is gathered upon the conspicuous 

 brushes of the first tarsal segments or plantaj of these legs. 



In taking pollen from a foreleg the middle leg of the same side is ex- 

 tended in a forward direction and is either grasped by the flexed fore- 

 leg or rubbed over the foreleg as it is benf downward and backward. 

 In the former movement the foreleg flexes sharply upon itself until

the tarsal brush and coxa nearly meet. The collecting brush of the 

 middle leg is now thrust in between the tarsus and coxa of the fore- 

 leg and wipes off some of the pollen from the foreleg brush. The 

 middle leg brush is then raised and combs down over the flexed fore- 

 leg, thus removing additional pollen from the outer surface of this 

 leg. The middle leg also at times reaches far forward, stroking down 

 over the foreleg before it is entirely flexed and apparently combing 

 over with its tarsal brush the face and mouthparts themselves. 

 "V\Tien the middle leg reaches forward to execute any of the above 

 movements the direction of the stroke is outward, forward, and then 

 back toward the body, the action ending with the brush of the leg in 

 contact with the long hairs of the breast and with those which spring
