Social parasitism behavior between two species of edible wasps in China

We reported the social parasitism behavior between Vespula structor and Vl. flaviceps for the first time. These two Vespula species are both popular edible wasps in southwest China. Such a nest with these two mixed Vespula species in their natural state was found in the field, and observations both in situ and in doors were performed. Workers of the two Vespula species have distinct different looking but possess similar antennal sensilla. Mitochondrial DNA analysis proved these two Vespula were indeed two different species, with genetic difference of 14
