Cluster fly foot. Coloured scanning electron micrograph (SEM) of a pulvillus on the foot of a cluster fly (Pollenia vespillo). A pulvillus is a rounded pad used to walk on smooth surfaces. It is covered in tiny tubular structures that secrete an adhesive liquid. When walking on rough surfaces, the two long, hooked claws (not seen) are used. Magnification: x575 at 6x7cm size.
