Shape differences rather than size differences between castes in the Neotropical swarm-founding wasp Metapolybia docilis (Hymenoptera: Vespidae, Epiponini)

Table 3 Discriminant morphometric variables between queens and workers in Metapolybia docilis based on discriminant function analyses using the stepwise procedure and classification results for group comparisons through discriminant analysis. Original data are based on mm.
