Table 2 Eigenvectors from PCA of independent contrasts of silk gland characters and spinning behaviours for seven species of Embioptera. Two principal components account for 77% of the variation, three for 93%. See Table 1 for details of morphology and behaviour measurements. PC1 and PC2 are significant at P < 0.001 and 0.018 respectively.
