Diet composition of two Polistes wasp species from urban and sub-urban areas of Auckland (New Zealand), based on DNA analyses of larval faeces in nests (n = 88 for P. chinensis; n = 8 for P. humilis) a Frequency of occurrence of different invertebrate orders in the diet of P. chinensis (left) and P. humilis (right) b Relative read abundance of prey taxa as measured from each individual faecal sample (i.e. for each individual wasp larvae) in inner and outer cells of the nest. c Occurrence of the different prey genera, in the diet of each individual wasp larvae.
