Insect Architecture. 



In the second, and on the left-hand side, is a very long 

 and simple tube, made of a grass stem, and balanced by three 

 little sticks attached to its centre. The next figure represents 

 a number of sand-tubes attached to each other. These are 

 built up laboriously of single particles of sand, and are 

 remarkable for their peculiar horn-like shape, the tube 

 having the same regular curve as the horn of an ox or 

 antelope, and tapering gradually from the base to the top. 

 A somewhat similar tube, but of larger size, is shown in the 

 right-hand figure. 



Any one who wishes to see one of these creatures rebuild 

 its house can do so by carefully removing it from its tube, 

 and supplying it with fresh material. Very great care must 

 be taken in the removal, as the grub is easily damaged, and 

 it holds so tightly to the tube with a pair of pincers at 

 the end of its body, that it must rather be coaxed than 

 driven out. 



If desirable, they can be made to build their new houses
