372 AFFECTION OF INSECTS FOR THEIR YOUNG. 



society, and that with an ardour of affectionate attach- 

 ment to which, when its intensity and duration are taken 

 into the account, we may fiiirly say there is nothing pa- 

 rallel in the whole animal worlds Amongst birds and 

 quadrupeds we have instances of affection as strong per- 

 haps while it lasts, but how much shorter the period du- 

 ring which it is exerted ! In a month or two the young 

 of the former require no further attention ; and if in a 

 state of nature some of the latter give suck to their off- 

 spring for a longer period, it is on their parts without 

 effort or labour; and in bodi cases the time given up to 

 their young forms a very small part of the life of the ani- 

 mal. But the little insects in question not only spend a 

 greater portion of time in the education of their progeny, 

 but devote even the whole of their existence, from their 

 birth to their death, to this one occupation ! 



The common hive-bee and the wasp in their attention 

 to their young exhibit the same general features. Both 

 build for their reception hexagonal cells, differing in size 

 according to the future sex of the included grubs, which 

 as soon as hatched they both feed and assiduously tend 

 until their transformation into pupae. There are pecu- 

 liarities, however, in their modes of procedure, which 

 require a distinct nodce. 



The economy of a nest of "d'asps differs from that of 

 bees, in that the eggs are laid not by a single mother or 

 queen, but by several; and that these mothers take the 

 same care as the workers in feeding the young grubs : 

 indeed those first hatched are fed entirely by the female 

 which produced them, the solitary founder of the colony.
