Fig. 3 A. 3D in Is the copulation of silver-washed fritillary inverted? Function of the female genital projection (Lepidoptera: Nymphalidae: Argynnini)

Fig. 3 A. 3D reconstruction of the cornucopia and its related structures during copulation. B. Ditto, with cornucopia transparent. Blue arrowheads indicate broken cornuti; red arrowheads indicate the spines of the uncus penetrating the cornucopia. C. Internal structures of the cornucopia (orange: ductus seminalis; orange arrowhead: opening of ductus seminalis; yellow: muscles). White broken arrows indicate the direction of muscle fibres. Muscles are only reconstructed posterior to the ductus seminalis opening. D. SEM image of the opening of the ductus seminalis (scale = 0.1 mm)
