BREEDING LARVAE. 



BREEDING LARVAE. 



The finest specimens of Lepidoptera are obtained by 

 rearing from the larval or pupal stages. This is accomplished 

 by the use of breeding cages. For this purpose glass tum- 

 blers covered with gauze may be employed, but a better thing

is a box especially prepared for the purpose. Take a wooden 

 box without a cover, lay it on its side and tack a lath across 

 the lower edge so that a shallow tray is made ; then cover 

 the rest of the opening with gauze or mosquito netting- 

 Then put a small door in the side, which, by the inversion of 

 the box, becomes the top. The box should then have a layer 

 of moist earth reaching to the top of the lath. It is fre- 

 quently well to subdivide the box as larvae are occasionally 

 apt to desert a vegetable diet and eat their companions.
