Scanning electron micrograph of a foot of a housefly,Musca domestica. The foot of the fly consists of two claws (above,antlerlike) & two pads or cushions called pulvilli (below,white). The foot serves a dual purpose; on rough surfaces the claw grips & on smooth surfaces the miniature tubes covering the pads secrete a substance,which enables adhesion. It is uncertain whether the tubes secrete a glue or whether physical effects of surface tension & molecular action account for the adhesion. Many of the hairs,or setae,on the insect serve as tactile sensory organs. Magnification 760 (at 10x8 inch size) | |
