FIGURE 4. Principal component analysis. a—Factor loadings of principal component analysis (BL: body length; HL: head length; HW: maximum head width; HW2: head width at the posterior bend; TL: thorax length; PTL: 1st thoracic segment length; AL: abdomen length; SA1L: antennal sensory appendix I length; SA1W: antennal sensory appendix I width; SA2L: antennal sensory appendix II length; SA2W: antennal sensory appendix II width;); b—Factor scores of the examined populations on the first two principal component; c—Factor scores of the two species on the first two principal component.
