Rearing Insects in General. 



More attention has been paid by entomologists to rearing 

 caterpillars than the young of any other orders of in- 

 and the following remarks apply more particularly to them, 

 hut very much the same methods may be pursued in rear- 

 ing the larvae of Neuroptera, beetles, flies, and Bymen- 

 optera. Subterranean larva? have to be kepi in moist earth, 

 aquatic larva' must be reared in aquaria, and carnivorous 

 larvae musl be supplied with flush. The larvae of butter- 

 flies are asually rare; those of moths occur more frequei 

 while their imagos may be scarce. In some years many 

 larvae, which are usually rare, occur in abundance, and 

 should then be reared in numbers. In hunting for cater- 

 pillars, bushes i hould be shaken and beaten over newspapers 

 or sheets, or an umbrella; herbage should be .-wept, and 

 trees examined carefully for leaf-rollers and miners. The 

 specimens of moths and butterflies are obtained by 

 rearing them from thi 'orfrom the larva or pupa. In 



Lepidoptera lay on the average from 100 to 70 

 butterflies should be looked for on the herbs, bushes, or trees about 

 which they fly; those of sphinges on the fl( risitod bj
