 her nurselings want is a mess of Flies that

 sides, head, thorax or belly, according to the 

 chances of the scuffle. The Hunting Wasp

 directs his scalpel with a skilled hand; the 

 Social Wasp killing her prey behaves like a 

 common assassin who stabs at random. For 

 this reason, the Eristalis' resistance is pro-
