摘要:
The results of a morphological and morphometric comparison between two species ofPolistesobligate social parasites and their two respective host species are reported. Some parts of the body of the parasites were found to be larger than those of their hosts. Probably, such morphological traits are an advantage to the parasites during the nest invasion fights, e.g. the size of the mandibles which they use as a weapon against the foundress and workers.
