HOW TO KNOW THE BUTTERFLIES

 larvae of moths are reared they may have a 

 chance to go into the ground to transform. 1 



Branches of the proper food plant should be 

 stuck into bottles or cans which are filled with 

 sand saturated with water. By keeping the sand 

 wet the plants can be kept fresh longer than in 

 water alone, and the danger of the larvae being 

 drowned is avoided by the use of sand. 



Hibernating chrysalids may be left in the 

 breeding-cages or removed and packed in moss 

 in small boxes. Great care should be taken to 

 keep moist the soil in the breeding-cages, or the 

 moss if that be used. The cages or boxes con- 

 taining the pupa; should be stored in a cool cellar, 

 or in an unheated room, or in a box placed out 

 of doors where the sun can not strike it. Low 

 temperature is not so much to be feared as great 

 and frequent changes of temperature. 



An excellent breeding-cage can be made by 

 combining a flower-pot and a lantern-globe or a 

 large lamp-chimney ; the top of the lantern-globe 

 is covered with Swiss muslin.
