in the refuse under the comb and this mass of webs afEords an excellent 

 protection' to the p\ipa. The most common places are cracks or corners 

 about the hive, or between the frames and the hive or in the "hee 

 space" at the end of tlie top bars. The larva prefers to get into a 

 place which' it can chew in order that a cavity may be constructed and 

 the cocoon thus be better protected. 



Having found the location for the cocoon, the larva begins the spin- 

 ning of the silk thread about itself, starting just above the head and 

 working backward more than the length of the body. A thin layer of 

 silk is spun in the general shape of the cocoon and this frame work is 

 covered with fine silk from the inside. The larva is able to reverse 

 itself within the cocoon, which it does many times during its con- 

 struction. The outer layer, upon hardening, becomes very tough, and 

 even like parchment, while the inner layer remains soft and flufEy. 



CONSTRUCTION OF COCOON 



The time consumed in the spinning varies with the season and varies 

 most in the cooler portions of the year. Within the brood there is some 

 variation.

The average period of construction of the cocoon of this brood was

 normal temperatures.
