Fig. 13From: Immature instars of three species of Rhodnius Stål, 1859 (Hemiptera, Reduviidae, Triatominae): morphology, morphometry, and taxonomic implicationsScatter plots of the canonical variate analysis (CVA) of the grouped matrices for geometric morphometric of heads. The scores of the first canonical variable (CVA1) are on the x-axis and the scores for the second canonical variable (CVA2) are on the y-axis. The ellipses represent the confidence for means limits of each population (probability 0.5). (R. marabaensis—black ellipses; R. prolixus—red ellipses; R. robustus—blue ellipses). a first instar; b second instar; c third instar; d fourth instar; e fifth instarBack to article page
