After the adults have rapidly emerged from the parent nest 

 in a vast swarm and have flown a short distance in an irregular, 

 wobbly manner, they fall to the ground. As soon as they reach 

 the ground, they cast the wings. Then the male is attracted 

 to the female and follows her tirelessly and closely, performing 

 the so-called "Termiten Liebes-Spaziergang." In this manner 

 the imagoes separate into pairs and enter hiding places in order 

 to establish new colonies, usually under pieces of decay- 

 ing wood, in holes and crevices in wood, or directly in 

 the earth. 



In order to observe the starting of a new colony, many 

 new couples were captured in glass tubes, arranged as 

 shown in fig. 1. 



The bottom of a test tube, 2 by 16 centimeters, is bored 

 with a capillary pore, and a piece of absorbent cotton, 



a, is inserted. Then a proper quantity of crushed clay, 



b, is placed in the tube to serve as the abode of the fu- 

 ture colony ; upon this layer pieces of soft wood or cotton, 

 a, are laid for food. A male and a female that have 

 recently flown from the nest are now placed in the tube, 

 which is tightly corked and put in a dark place. 



In order to keep captive termites in a healthy condi- 

 tion, it is absolutely necessary to give them proper hu- 

 fic. i. midity. This is done by placing the end of the tube in 

 water, thus allowing the absorbent cotton to draw a 

 sufficient amount of water through the pore. As a result of 

 these investigations, the following facts were determined: 



1. During the first stage of colonization both the male and the female 



are active. They forage for themselves and are equally important 

 in establishing the new colony and in rearing the first brood of 

 young. 



2. Egg laying in a newly established colony begins from five to thirteen 



days after the swarming.
