20 INSECT ARCHITECTUKE. 



When an insect first issues from the egg, it is culled 

 by naturalists larva, and, popularly, a caterpillar, a 

 CTUb, or a maggot. The distinction, ill popular lan- 

 guage, seems to be, that caterpillars are produced 

 from the eggs of moths or butterflies ; grubs, from 

 the eggs of beetles, bees, wasps, &c. ; and maggots 

 (which are widiout feet), from blow-flies, house-flies, 

 cheese-flies, &c, though this is not very rigidly ad- 

 hered to in common parlance. Maggots are also 

 sometimes called worms, as in the instance of the 

 meal-worm ; but the common earth-worm is not a 

 larva, nor is it by modern naturalists ranked among 

 insects. 



Larvie are remarkably small at first, but grow 

 rapidly. The full-grown caterpillar of the goat-moth 

 (Cossws ligniperda) is thus seventy-two thousand 

 times heavier than when it issues from the egg ; and 



Larva, drubs. Caterpillars, or Maggots.
