70 LIFE IN THE INSECT WORLD. 



The larvae of butterflies and moths are called 

 caterpillars ; those of beetles, bees, wasps, &c., 

 grubs ; and those of flies, maggots. Many peo- 

 ple, however, call the whole race worms ; but 

 entomologists, by which I mean those who un- 

 derstand the science of insects, which is called 

 Entomology, generally make these distinctions. 



ftnna. Are moths and millers the same ? 



Jlunt M. Yes ; moths are frequently called 

 millers. 



Harriet. What is the difference between 

 butterflies and moths ? 



Jlunt M. One of the most important distinc- 

 tions between them is, that butterflies fly only 

 in the day, and moths generally fly at night. A 

 few species of moths, however, may frequently 

 be seen in the day-time. There is a difference, 

 also, in the form of their antennae ; those of 

 butterflies being thicker at the end, while those 

 of moths are pointed. 



The chrysalides of moths are generally wrap- 

 ped in cocoons of silk, and are mostly somewhat 

 egg-shaped ; while those of butterflies are with- 

 out this silken covering, and are of different 

 forms.
