with honey, and lays her egg. At that mo- 
ment the little larva quits the Bee and jumps 
on to the egg, which she proceeds gradually 
to devour. Having finished the egg, she 
attacks the honey; but under these circum- 
stances the activity which was at first so 
necessary has become useless; the legs which 
did such good service are no longer required ; 
and the active slim larva changes into a white 
fleshy grub, which floats comfortably in the 
honey with its mouth just below the surface. 
Even in the same group we may find great 
differences. For instance, in the family of 
Insects to which Bees and Wasps belong, 
some have grub larvee, such as the Bee and 
Ant; some have larve like caterpillars, such 
as the Sawflies; and there is a group of 
minute forms the larve of which live inside 
the eggs of other insects, and present very 
remarkable and abnormal forms. 
These differences depend mainly on the 
mode of life and the character of the food.
