Table 1. Veins lengths extracted from Dolichovespula sylvestris and Dolichovespula saxonica wings. Students t test was used to compare veins lengths between species. The veins were named according to junction numbers (Fig. 4) between which they were located. All individuals were classified accurately by discriminant function analysis based on 12 veins.
