Monochamus alternatus attached to different substrates at different positions: horizontal (a, d, e), vertical, upwards (b), and ceiling (c, f). a, c. Glass plate. b. Glass rod. d, f. Pine twigs (bark). e. Pine needles (leaves). g. A female clamps a bulk of several needles shaping some larger rod-shaped structure between their legs. h. A male grasping a female during copulation. Tarsi of fore- and middle legs adhere to the elytra, while the hind legs keep in contact with the substrate, but not with female’s body
