Abstract: A scanning electron microscope was used to observe the structures of the setae o n the surface of a dung beetle Coprisochus, Motschulsky. There are lots of seta e on the body surface, especially on the ventral part surface and lateral to the legs which are different in size, arrangement and shape. These setae have different lengths and many thorns on the whole seta. The top ends of these setae stand up without furcations which direct uprightly towards the surface of the touched soil. By the method of removing these setae, getting the insect weigh t before and after digging into the dung we affirm farther that the setae on the beetle body surface form the anti-stick and non-adherent gentle interface. The soil machines and components made by imitating the gentle body surface of beetle s have favorable non-adherent results.

Key words: seta, dung beetle, flexible surface, scanning electron microscopy, bionics, soil adhesion
