98 THE BUTTERFLY VIVARIUM. 



lusion to its destruction of the wax of the honey- 

 comb. The Oalleria genus contains no other British 

 species. 



Most of the habitations framed by larvae for 

 protection during the pupa state are, more or less, 

 nearly close fitting, and these may perhaps be con- 

 sidered rather in the light of clothing, while others 

 more roomy may rather be considered as residences. 



The woollen tubes formed by the larvae of 

 various small Moths of the Tinean family are very 

 curious, and an interesting effect may be produced 

 by guiding their industry after a certain manner. 

 For instance, by carefully placing the larvae succes- 

 sively on cloths of different colours, their case will 

 become variegated by the new material, each time 

 they enlarge it to suit their increased growth. A 

 very richly coloured tube is thus produced by the 

 successive addition of blue, red, green, white, or any 

 other coloured cloth that may have been selected. 

 The garment of many colours so formed is a very 

 pretty object when examined with the aid of a 

 powerful microscope, and the experiment is well 

 worth trying. 



Some of the small larvae which feed on the blos- 

 soms of the kind of willows that generally grow on 

 the banks of ponds or streams, make their houses
