Principal components analysis is performed on 11 variables of Polistes exclamans nests, brood and associated adults in nest collections made in June, July and September. Four biologically meaningful principal components were found: (1) nest size, (2) nest growth, (3) nest decline, and (4) nest parasitism. In each sample nest size accounted for most of the variance, followed by nest parasitism. Comparisons among populations using principal components values instead of individual measures make more complete use of available information.
