Stereoscopic examination of a cleared A. vulgare. a Dorsal view of a cleared male (left) and female (right). Most of the body parts became transparent, except for the sperm vesicle (Sv), vas deferens (Vd), mandibles (M), and pseudotrachea (Pt). Scale bars = 2 mm. The boxed region on the female is shown in b at higher magnification. b Junction of anterior (Ah) and posterior (Ph) hindgut. A pair of typhlosole channels (Tc) run along the dorsal midline of the anterior hindgut. Scale bar = 1 mm. c Muscle striation in a leg. The boxed region in the left panel is enlarged in the right panel. Scale bar = 500 μm (left), 200 μm (right). All observations were performed under appropriate oblique illumination
