300 INSECT ARTIZANS AND THEIR WORK 



the spiracles becoming clogged. The only exertion 

 demanded of it is the sucking up of the honey, and 

 there is enough of this to occupy it for about forty 

 days. 



This brings it to the middle of July, when it 

 changes again, becoming much like the puparium 

 of a fly. In this condition it may remain for a 

 month, or for eight months. Those of the shorter 

 period return to much the same condition as 

 that in which they consumed the honey. A little 

 later it becomes a chrysalis, and in August or 

 September it emerges as a Sitaris beetle. The 

 tardy individuals pass the winter in the false pupal 

 condition, and finish their changes in spring. 

 This, it will be seen, is one of the most complicated 

 and remarkable of insect life-histories.
