(A) A female M. sexta. Red lines mark regions along the wing margins where sensory scales and sensory bristles were found. (B) Light microscopy image of the margin of a female forewing. Arrows, sensory bristle. Asterisks, sensory scale. (C) Left: scanning electron microscopy (SEM) image of a sensory scale (asterisk). Right: enlarged view of the tip. (D–G) SEM images of sensory bristles on the forewing and hindwing margins of a female (D,E) and a male (F,G). Left: sensory bristles (arrows). S, socket. Right: enlarged view of bristle tips (filled arrowheads, subapical pores; open arrowheads, pores). ------ Max Planck Institute for Chemical Ecology Hawk moths have a second nose for evaluating flowers - Max Planck Neuroscience, 27.07.2026 https://maxplanckneuroscience.org/hawk-moths-have-a-second-nose-for-evaluating-flowers/
