The Geotrupes: the Larva 



looking for Scolia-cocoons in a heap of 

 mould, I had made a large collection of the 

 grubs of Cetonia aiirata.^ I placed my loot 

 in a flower-pot with a few handfuls of de-

 the insects' backs. I intended to draw upon 

 them for certain enquiries which I was ma-

 ill-protected against this kind of weather. I 

 found the contents of the pot hardened into 

 a conglomeration of earth, dead leaves, ice, 

 snow and shrivelled grubs. It was a sort of 

 almond-rock,' in which the larvae stood for 

 the almonds. Sorely tried by the cold as 

 they were, the colony ought to have perished. 

 But no : when the thaw arrived, the frozen 

 larvae came to life again and began to swarm 

 about as though nothing unusual had hap-

The insect's powers of endurance are less 

 great than the larva's. As the organization 

 becomes more refined, it loses its robustness.
